Possible to end up in Play mode with a higher than max zoom level

This issue has been migrated from mozilla/webmaker-android#1995.

It was originally written by flukeout on Fri May 22 2015 and had the following description:

Steps to reproduce

• Edit a project
• Enter play mode
• Tap a page to zoom in
• Exit play mode and go back to the editor
• Enter play mode
• The view is in "map view & pan mode", but the page size suggests the 'swipe zoomed in mode'
• When you attempt to zoom pinch from this state, the map zoom level immediately, and jarringly jumps back the max zoom level

We still have to sort out what zoom level and state we should start Play mode in though.

:+1: Good catch.
