Arlo Breault c068c166e2 Preserve link content for broken media
Parsoid will start populating the link content with the alt text if it's
available before falling back to the filename.  Preserving what's there
is needed to avoid dirty diffs during the transition and for cached
content.  In the future, we can remove errorText and replicate Parsoid's
new behaviour..
