It turns out that IMMS#SettingsObserver has monitored only main user's the secure settings. As a result, when the secondary user changes enabled IMEs in the settigs app, IMMS only updates internal enabled IME lists only when the user is switched for secondary users. If a secondary user enables or disables IMEs at the settings app, such changes are not correctly notified to IMMS. This CL addresses above inconsistency by explicitly specifying the user ID when calling ContentResolver#registerContentObserver(). This CL also allows dumpsys to contain internal state of IMMS#mSettingsObserver in case we need to diagnose problems only with bugreports.
