fix: android duplicates in linked packages

[thymikee]

Fixes #43

• Improved the Regex to be more forgiving in terms of spacing and implementation/compile names with variants and configs
• add more thorough test
• cleanup makeBuildPatch test to not test implementation details
• cleanup link test so it doesn't output to stdout unnecessarily
• tested on a project I had issues with duplicates (resolved with this diff)

@grabbou thanks for making me aware of this PR!

These changes are solid but it doesn't seem to address the unlink issue. makeBuildPatch still returns an "implementation" patch string, so a previously linked "compile" dependency would not be successfully unlinked.

Let's say we want to unlink a "compile" dependency that was linked way back. When the revokePatch function is called in unregisterNativeModule.js#L41 it will look for an "implementation" string to replace with an empty string but, since we have a "compile" dependency, our dependency entry in the Gradle file will never be found and thus it would not be removed.

I can try to move my old PR from the RN repo to this one and continue the discussion there if that would be better 😄
