Fix build_nr in tsp/jobs/trigger_downloads.sh

If a url is present in tsmaster queue $i value will be changed
to last killed task's number or simply undefined value.

Rename $i to $next
Add update_next() which checks if write to a file was successful.
Append to unique_dispatch instead of overwrite.
