fix(deluge-labels): non-static label support during injection (cross-…

…seed#540)

# Deluge Labels

## Purpose

this mirrors the qbittorrent behavior where a matched torrent's label
will now be used during injection (if a label is set)

- [x] duplicateCategories (true) will append ".cross-seed" to the same
label.
- [x] dataCategory will be used for data-based matches
- [x] if "No Label" is set, default will be "cross-seed"

Closes cross-seed#538
