Work around AbsListView.confirmCheckedPositionsById() not respecting adapter count.

When restoring instance state, AbsListView tries to reconstruct the
checked positions from checked ids saved in instance state, however it
didn't take changing adapter content into consideration so that it may
call Adapter.getItemId() with a position greater than or equal to
Adapter.getCount(), breaking the contract.

We can work around this by returning ListView.INVALID_ROW_ID when
getItemId() is called with an invalid position, and since we are
already manually restoring the checked item (because we need to
differentiate between a user-checked item v.s. an item checked because
it's current default), it's okay to lose the checked state restoration
provided by AbsListView.

Test: Enable "Don't keep activities" in Settings, open an app that
      requests a role, select an item in list and switch apps back and
      forth. This way RequestRoleFragment is crashing before the fix,
      and not crashing after the fix. State is also still preserved
      after rotation after the fix.
