Make tag API for release feature consistent

Make tags API consistent with other tags methods. This changes the endpoint from `PUT /projects/:id/repository/:tag/release` to `PUT /projects/:id/repository/tags/:tag_name/release`.

On thing the API is still missing, is an error if the tag does not exist. Right now it returns 200 even the tag does not exist. I'll fix that such it returns 404.

@stanhu Can you review?
@rspeicher This MR should go into 8.2

Check which folders and archives should be packed before passing to tar command.

If user uses backup task with SKIP and skips one of the archives listed(uploads, builds, artifacts) backup create will give an error: `Cannot stat: No such file or directory`.

This MR fixes that by checking for skipped items.
Additionally, compact everything to avoid `TypeError: no implicit conversion of nil into String` errors.
