During imports, the BatchIndexer isn't flushing all the ming sessions properly, so some artifacts (e.g. last ticket in a trac import) aren't in that add_artifacts
task. That artifact then gets picked up later in a subsequent import's BatchIndexer session. So then when that add_artifacts
task runs, the ticket is from the previous project but the context is this new project. As a result, artifact shortlinks will get resolved to the current project instead of the first project, and then the "related artifacts" will be wrong for that ticket.

I manually tested this behavior by importing tickets for https://sourceforge.net/apps/trac/mcclidar and then finding the add_artifacts task at /nf/admin/task_manager/ and seeing if it had the _id matching
db.ticket.find({ticket_num:49, app_config_id: from_url('/p/testit/tickets-mcc-batch2')._id}).next()._id
