Refresh carrier info on SERVICE_PROVIDERS_UPDATED

For reasons out of scope for this CL, it's demonstrably possible that we
can get the SERVICE_PROVIDERS_UPDATED broadcast after other events that
cause KeyguardUpdateMonitor to call `refreshCarrierInfo` on the
callbacks. This means that it's possible that the carrier text changes
in the system, but CarrierTextManager never queries the new state.

This CL adds a listener to that broadcast and hooks it up to
`refreshCarrierInfo`.

Test: remove SIM while QS is expanded
Test: KeyguardUpdateMonitorTest
