Allows the two menu items "Ignore All Updates" and "Ignore This Update"
to be checked and save the relevant preferences to the database in response.
The old code waited until the activity was paused before saving the
preferences to the database. This code does not, and as such incurs
a database write on the main UI thread as soon as the user checks the
menu items. However that database code has recently been refactored so
it should be much more performant. If it turns out to still be problematic
then we can revert to the old behaviour of hodling onto any state changes until
onPause then persisting to the database.
