chore(abg): Unify content of ActionCoords name

[Vampire]

Before these changes, ActionCoords#name sometimes had the actual action coordinates, so for example some-name__some-sub, sometimes it had the replaced some-name/some-sub. This is not good, as you never know what you get and also led to certain bugs where wrong things are written to metadata files for example. This changes unifies the situation, so that the name only contains the repository name and the path is in a separate property with slashes. All other manipulation is then done where needed.
