Fix crash with decorated custom notifications

Clones notifications before adding them to remote views so
the original stays parcelable on its own.

Also prevents the compatibility inflation from triggering when
an app uses a decorating style to prevent recursive wrapping.
Those styles only exist on N and later anyways.

Also fixes the compatibility inflation in listeners.
