Don't attempt to configure a dismissed dialog during Android activity

Browse Source 
reloading

As part of automatic activity reloading following a configuration
change, Android invokes Activity#onPrepareDialog() even for dismissed
dialogs. Consequently, one can't make the assumption that this method
is only invoked by explicit calls to Activity#showDialog() from our
code.

The actual problem here was the mActiveMessages member being null
at such times.
