fix(communityTests): find the correct module by test name

Fix a bug for community tests where the test and module name are not the same. Eg: test is `csspositionsticky` but the module is `css-positionsticky` so it cannot find the correct test file.

It is not a good idea to add tests for community tests as it takes a long time to download all the files (this might be the cause of the bug) unless refactoring the tests. I can do it if it's needed :)
