The number of Koji build jobs triggered when using sidetags can be overwhelming

For example, this is from the last release of Packit:

There are two issues here:

• The builds without a task ID are in skipped state because of missing dependencies, but perhaps it could be possible to check for the dependencies earlier and not record the builds in the DB at all.
• The purple builds with a task ID are in pending state, but they shouldn't be there at all, each of them complements a successful build that was for some reason triggered for a second time. Another issue is that their state should be error rather than pending (the tasks failed with GenericError: Build already in progress).
