Auto-branch detection with Github seems problematic in 4.4

I'm working on replicating the issue, but to wit:

We upgraded to 4.4 a week ago, and have branch detection for several Github-based projects checking for (release)/.*

Noticed that when I branched to release/february, the auto-detect picked up the branch, but had the actual Github branch set to develop, not the release branch, and more strangely, seemed to be picking up multiple copies of the same branch (release-february, release-february 1, release-february 2, release-february 3, etc.)

I saw at least 8 branches get created before I turned off the auto-detection, so unsure whether this was an issue with cross-branch merges I was doing, commits to the branch, etc.

As noted above, I'm working on replicating this more thoroughly. Also wondering if this might be related to BAM-12770 and that the bamboo/github integration is out of date.

Just recording the issue for posterity.
