Fix Floating Toolbar appearing after ActionMode was cancelled

The Views created for the Toolbar were not cleaned up properly when the
mode was cancelled by the client in onCreateActionMode, leading to the
toolbar appearing over other views when it shouldn't due to
onWindowFocusChanged showing the Toolbar if it exists.

We don't actually need the views if we don't know whether they are
going to be shown yet, so moved view creation to after onCreateActionMode
