Remove redundant call of queryInputMethodServicesInternal (2nd try)

This is the 2nd attempt of submitting my previous CL [1], which got
reverted [2] due to a boottime regression (Bug 329414077).
We have already addressed the major contributor of the boot time
regression [3], so this CL should be ready to be submitted again.

To follow up my previous CL [4], which introduced
InputMethodSettingsRepository as a read-only mode again.

There was a redundant invocation of

  InputMethodManagerService#queryInputMethodServicesInternal,

in

  MyPackageMonitor#onFinishPackageChangesInternal().

This CL fixes it.
