Originally I was thinking that both addition should be bundled together; but thinking more about it - it is better to move the new addition to its own 'if' check. Updated.

This fixes issue #2607.
'RequiredModules' is a field in module manifest that can reference other modules using ModuleSpecification format.
The basic version of this format (just module name) was working fine, however there was a problem when more detailed version of the format was used (the one that uses module versions or/and GUIDs).
During module import, there is a check for cyclic references through 'RequiredModules' field. The bug was in this check for cyclic references , related to comparison rules for ModuleSpecification objects - as a result code was incorrectly reporting 'cyclic reference' error in cases when there was none.
Added tests for different ModuleSpecification formats and a test for error when there is actually a cyclic reference.
Test results before the fix:
