Cleanup linters baseline files

[Mugurell]

We currently have two baseline files used by the static analysis tools:

• for Android lint
• for detekt

which are used to ignore even new lint issues instead of them only serving as the list of initially caught issues when the static analysis tools were first integrated. Since ignoring issues caught in static analysis defeats the purpose and adding the ignores in the baseline files allow to forget about such issues we should look into resolving the issues and clearing the baseline files.

I noticed the lint-baseline.xml for several times, and I can reproduce the issues induced by android:lineHeight.
