Save draft new releases to local storage

What does this MR do and why?

All actions that save release data now update local storage. Only save released at date if it has been altered, as it will otherwise create a historic/future release when provided.

The createFrom ref needs to be saved separately, as it isn't in the draft release object.

All of this applies only to new releases.

Changelog: added
