When creating a bitmap using JGit, two packfiles are created:
1. All heads, excluding tags and non-heads
2. Everything else

The 1. is accompanied with a bitmap for all the commits included in it, excluding all non-heads and tags.

What I see is that *IF* a repository contains annotated tags, they are included in the bitmap. If the number of annotated tags is significant, the bitmap is so bloated to become unusable.

To reproduce the issue:
- Create a repository with 1 branch and 100 commits
- Set pack.bitmapContiguousCommitCount=1
- Create 100 annotated tags, one per commit

Expected behaviour:
- JGit GC create 1 bitmap for the single branch

Observed behaviour:
- JGit GC creates 101 bitmaps, one for the single branch + one per every annotated tag
