Apostrophe 4.11.2: hotfix for image selection bug

[boutell]

A recent version of Apostrophe introduced an issue where selecting images for a widget via the "Browse" button just didn't work. As it turns out this was caused by an interaction that is quite difficult to spot in automated CI tests. We've addressed the underlying issue.

This issue has been fixed in Apostrophe 4.11.2.

In addition, in 4.11.1 we took care of an unrelated mocha test that was failing, but no code changes were required, just an update to the test.

As a reminder, it is best to npm update your project as a whole for maximum compatibility. However if you already upgraded to 4.11.0 you shouldn't need to upgrade anything other than apostrophe itself to get this bug fix.
