Forms: Fix bindings to Flash, bottom, top text

Redth · Redth · commit 921e8dbd3415 · 2017-04-14T15:05:00.000-04:00
The binding context of the `ZXingDefaultOverlay` view was never set, so any attempts to change the visibility of the flash button or set the top/bottom text would cause it to not be visible, basically the bindings weren’t propogating.
