Summary
Testing HTTP Callouts from Async Apex fails after inserting a CollaborationGroup or SetUp objects like User , ContentVersion, and it throws "System.CalloutException"
Exception: System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out. The error also depends on sObject, Class version, and org shape

Repro
- Create the following classes and Run/Execute the test "CalloutAccountsTest".

- Class 1:
========
@isTest
public class SingleRequestMock implements HttpCalloutMock {
protected Integer code;
protected String status;
protected String bodyAsString;
protected Blob bodyAsBlob;
protected Map<String, String> responseHeaders;

public SingleRequestMock(Integer code, String status, String body,
Map<String, String> responseHeaders) {
this.code = code;
this.status = status;
this.bodyAsString = body;
this.bodyAsBlob = null;
this.responseHeaders = responseHeaders;
}

public SingleRequestMock(Integer code, String status, Blob body,
Map<String, String> responseHeaders) {
this.code = code;
this.status = status;
this.bodyAsBlob = body;
this.bodyAsString = null;
this.responseHeaders = responseHeaders;
}

public HTTPResponse respond(HTTPRequest req) {
HttpResponse resp = new HttpResponse();
resp.setStatusCode(code);
resp.setStatus(status);
if (bodyAsBlob != null) {
resp.setBodyAsBlob(bodyAsBlob);
} else {
resp.setBody(bodyAsString);
}

if (responseHeaders != null) {
for (String key : responseHeaders.keySet()) {
resp.setHeader(key, responseHeaders.get(key));
}
}
return resp;
}
}

- Class 2:
========
@isTest
public class CalloutAccountsTest{

@testSetup static void testData() {
CollaborationGroup cg = getCollabGroup();
insert cg; // comment or uncomment this line to test the behavior.
}

public static testmethod void testAccountCallout() {
SingleRequestMock fakeResponse = new SingleRequestMock(200,
'Complete',
'[{"Name": "sForceTest1"}]',
null);
Test.setMock(HttpCalloutMock.class, fakeResponse);

Test.startTest();
System.enqueueJob(new QueueableClientAPI());
Test.stopTest();
}

public static CollaborationGroup getCollabGroup(){
CollaborationGroup cg = new CollaborationGroup();
cg.Name='Unit Test Group-1';
cg.CollaborationType='Public';
return cg;
}
}

- Class 3:
========
public class CalloutAccounts {
public static List<Account> getAccounts() {
HttpRequest req = new HttpRequest();
req.setEndpoint('http://api.example.com/accounts');
req.setMethod('GET');
Http h = new Http();
HttpResponse res = h.send(req);
String jsonData = res.getBody();
List<Account> accounts =
(List<Account>)JSON.deserialize(jsonData, List<Account>.class);
return accounts;
}
}

- Class 4:
========
public class QueueableClientAPI implements Queueable, Database.AllowsCallouts {

public void execute(QueueableContext context)
{
System.debug('*******before CalloutAccounts.getAccounts()*********');
CalloutAccounts.getAccounts();
}
}

Workaround
Update the Call out apex class api version to less than 34.0 (Example: In the above repro, the class CalloutAccounts should be less than 34)
