Bug 35408: Fix import job link

After importing titles from a list there is a link to the background job
that is displayed.
This link points to /cgi-bin/koha/admin/background_jobs/:id
There is a route to this path in routes/erm.js, to redirect to the
correct URI /cgi-bin/koha/admin/background_jobs.pl?op=view&id=:id
However this link will not work if we are accessing it from outside the
ERM app/module, or if we are opening it in a new tab/window.

The idea was interesting, but does not work...

Test plan:
Create a new ERM local package, a new list (virtual shelf), add some
items to the list.
Go to E-resource management > eHoldings > Local > Titles > Import from a list
Click "import"
Notice the "see job" link and click it

=> Confirm that with this patch applied you can open it in a new tab
without getting a 404
