Hi. I ran into a problem when updating gitversion from 5.8.2 to 6.0.4 on our build server. The problem is that version for "old" branches (v-10, v-11, v-12) suddenly become to evaluate from tag inside default (master) branch. For example, master has the latest tag 20.1.5 and branch v-11 has its latest tag 11.7.0 so making a new commit into v-11 I expect to get version 11.7.1. So it was before upgrading to gitversion 6.0.4. After upgrade I have version 20.1.6.

I spent some time on reading release notes/breaking changes with no luck. Then I started to check commit by commit in version history to localize the problem and have come to #3441.

Consider taking https://github.com/destructurama/attributed repo as an example:

1. Clone it
2. Make branch test from tag 4.1.0
3. Type 1 symbol in readme to just make some commit.
4. Commit.

Now I expect 4.1.1 output from gitversion.

My results (with stripped out time marks and execution time to make diff cleaner):

1. b0f6c77 commit before Consider pre-release tags only when they matching with the label name on branch #3441:

Not OK, 5.1.0.

Since that commit I can observe such behaviour. I think that corresponding part of problem in logs can be seen here:

For some reason gitversion become to use default branch instead of working branch.

What is expected?

I expect gitversion to use tags from working branch when operating on that branch, not from default branch.

Steps to Reproduce

Consider taking https://github.com/destructurama/attributed repo as an example:

1. Clone it
2. Make branch test from tag 4.1.0
3. Type 1 symbol in readme to just make some commit.
4. Commit.
5. Run gitversion PATH_TO_CLONED_REPO /diag on b0f6c77 (outputs 4.1.1)
6. Run gitversion PATH_TO_CLONED_REPO /diag on bb071c0 (outputs 5.1.0)
