Remove extra saves from Edit step models

[masaball]

Each step of the edit process has its own model which interfaces with the avalon-workflow gem to perform updates. In avalon-workflow, the update method saves the object.

In all, or nearly all, of our models for the edit steps we explicitly save the media object as well. The resource_description_step saves the media object twice in certain cases (the update_attributes method performs a save, immediately followed by another save after exiting the if/else block). I am unsure how much overall this would reduce timings, but we should try to remove the extra saves so that each step is only performing one save.

The old avalon_workflow gem was saving objects, but then avalon was also explicitly saving. Removed the secondary save from avalon code.

I have tested the following actions: record creation, editing structure metadata, modifying access control, and adding a new section. All functionalities performed smoothly, with no issues encountered.
