`PopupActions` uses `StorageHelper` from the front end

[Elec0]

StorageHelper only expects to be used from the background script, but it appears PopupActions is calling it directly.

The messaging should be changed so the other PopupActions methods also receive the updated workspaces from the background script, like PopupActions.openWorkspace already does.

• PopupActions.renameWorkspace
