Subject: [PATCH] Listen to ACTION_UID_REMOVED only. DO NOT MERGE.

NMPS was listening to both ACTION_UID_REMOVED and
ACTION_PACKAGE_REMOVED, which not only was redundant but would also
cause problems when a package with shared UIDs was removed.

Fixes: 31375684

Change-Id: Iec006dbbec0e6298f1e568cbf81ed3672f61b7d2
(cherry picked from commit fdebbea401dc9d38b0cbea0fdfbd758e16805358)
