Automated response: edit_gallery trying to find gallery by new name instead of old name

The edit_gallery function was trying to locate the existing gallery by new codename when it should have been using old codename (new codename does not exist yet if renaming).

A hotfix (a TAR of files to upload) has been uploaded to this issue. These files are made to the latest intra-version state (i.e. may roll in earlier fixes too if made to the same files) - so only upload files newer than what you have already. If there are files in a hot-fix that you don't have then they probably relate to addons that you don't have installed and should be skipped. Always take backups of files you are replacing or keep a copy of the manual installer for your version, and only apply fixes you need. These hotfixes are not necessarily reliable or well supported.
