Prevent re-use of dismissed wallet view

Rotation is disabled when wallet view is shown, but other interactions
(ie with Android Auto) cause ui mode change. Preventing re-use of the
wallet view controller after it has been dismissed ensures that the view
will not be re-attached to a different parent.

Fixes: b/162676641
Test: atest GlobalActionsDialogTest
Test: manual - enable rotation when wallet is shown (code change) and rotate.
