Polling crashes when real build is untagged

[mizdebsk]

I've untagged real build in Koji, which lead to polling crash. I'm using koschei-backend-2.3.1-1.fc28.noarch.

Traceback:

Do you have a link to the build?

Do you have a link to the build?

No. The Koji instance was transient and it's already gone.

Actually, that gives me enough pointers. There were probably imported builds (no repo_id) involved.
