Fix SystemCaptionsManagerService to re-bind after a force stop

This change also fixes a bug in AbstractMasterSystemService where
following a "force stop", the per-user service was not updated if PACKAGE_RESTART_POLICY_REFRESH_EAGER was specified. These behavior resulted with getServiceComponentName returning null and the service not being restarted.
