[dw-free] optimize viewing entries with large # of comments

[fu]

[commit: http://hg.dwscoalition.org/dw-free/rev/6121fc84a811]

http://bugs.dwscoalition.org/show_bug.cgi?id=4315

When we set _loaded_text back to false, make sure we also add this comment
back to the list of unloaded text singletons (we don't appear to go down
this path for anything user-facing at the moment, as we always set both
when editing comments but better safe than sorry)

Patch by fu.
