Scoped packages are starting to be the new thing, and gradle does not work properly with '/' in the project name, so this PR links them and replaces '/' by '_' . This only affects android.

I added tests in the 2 impacted functions + a test file for the normalizer function

[CLI] [BUGFIX] [local-cli/link/link.js] - On android, Scoped packages will now get the '/' replaced with '_' to ensure gradle works nicely.  ⚠️ However if you previously linked scoped packages, they will get linked again. ⚠️
