Aloha.settings.DrupalUI.renderOwnToolbarContainer is insufficiently advanced

The changes made over at #1760386: Migrate Aloha Editor integration from the Edit module and make it work on the back-end to distinguish (Aloha.settings.DrupalUI.renderOwnToolbarContainer) between Aloha inside forms vs. inside Edit module assumed it would be either of both cases on a page, but it's possible to have both! I'll have to figure out a way to enable both.
