Themes: Allow changing theme to Holo.Light without crashing

Themes that attempt to change the settings theme's parent to
Holo.Light will end up crashing wifi settings.

Themers should override Theme.Settings.Base and leave Theme.Settings.Holo
alone.  Attempting to theme Theme.Settings.Holo will result in crashes
when accessing wifi settings.

This was patch was adapted from

Keydisabler: fix button light restore logic

Do not assign default button brightness if backup key is not found.
Instead do nothing. This will prevent brightness being reset to default
on boot when navbar is disabled.

If backup key is not found when actually toggling navbar then we've got
bigger problems.
