Fix layout recreation check

Change I7d6b088a9235362e03cb6694392df71bbf5a323a added a relayout
for programmatic text direction changes, but this is breaking some
fixed layouts. Make sure layout params exist before trying to
act on them

Don't cleanup overlay mapping for non-theme apps

mOverlay structure should keep all app/theme mappings even
if the app does not exist. Otherwise we will have to insert back the mapping
for every app that is installed which would be time consuming.

Without this patch an upgrade app loses its applied theme
until the device is rebooted.
