Onboarding : 2 issues during "customize medialibrary folders"

Description

During onboarding, when you customize your medialibrary folders, 2 issues appears :

• The cross icon at the top left corner shouldn't be a left "chevron" ? Because you go back each time you click on it.

• The FAB Play button appears... and you can click on it...

Both issues have been fixed:

The cross icon at the top left corner shouldn't be a left "chevron" ? Because you go back each time you click on it.

The cross is meant to close the fragment. This behavior has been fixed. To navigate back, the [back] key/gesture can be used as well as the breadcrumb view.

The FAB Play button appears... and you can click on it...

The FAB is now hidden in both Onboarding and Preference screens
