Switch applyThemeOverlays slightly earlier, before view creation.

Some views and drawables were being created within super.onCreate
and before the derived class set their content view. This was very
problematic if those views used resources that were supposed to be
override by theme overlays, such as dynamic colors.

This change will apply the theme overlays just barely before onCreate,
allowing the correct values to be read.
