Urgent Fix to merged PR #3969
Issue: Tried to accomplish an issue raised by @auraz where I should factor out variables for the annotation tools. Basically

textannotation_module.py,imageannotation_module.py, andvideoannotation_module.pyeach had instances ofannotation_storage_url,annotation_mode, etc. I tried to compile them all intoannotator_mixin.py. Thought it had worked and pushed the fixes but it turns out that if you go to studio you get the following message anytime I hit "Edit" for image, text and annotation components in studio:Basically those 4 files got reverted to how they were before commit 3bfb633.
It was made known to us less than an hour ago that the file openseadragon.js we were using was using a different api call then the server so this is a 2-line change to make it work while we upgrade.
