control: Catch GetManagedObjects exceptions

The get_managed_objects action makes a GetManagedObjects D-Bus call to
put D-bus properties from a service into the cache.

Handle exceptions thrown by it in case it was called from a
name_owner_changed trigger when the service went off of D-Bus, which
would cause it to fail.
