mod_http_upload: Fix issuing slots to components or other non-c2s sessions The 'full_jid' property only exists on local c2s sessions. This was not adjusted for in 0a56dc6c61af, so it did not work. Thanks Fren__ for highlighting the issue.

This module writes out a traceback to `traceback.txt` in Prosodys data
directory (see `prosodyctl about`) when the signal `SIGUSR1` is
received. This is useful when debugging seemingly frozen instances in
case it is stuck in Lua code.
