Change Details

`renderValue()` repeatedly fails when passing the array `$old` instead of a string. Thus pass `(string)head($old)` instead. Closes T15646

Premising that the `$old` and `$new` variables are 1-element arrays defined as PHID=>title, this can cause `renderValue()` repeatedly fail when passing an array instead of its value. Thus pass `head($old)` instead, to get the first value - that is the only one, even if you rename multiple images (since this Transaction is about a single Mockup image). Closes T15646
