Description of the problem, including code/CLI snippet

Method project.commits.list(get_all=True) does not return commits from all branches.
I tried it with parameters as weel, but with no success:

commits = project.commits.list(get_all=True, since='2026-05-17 00:00:00', until='2026-05-18 22:20:00')

It returns only commits from default "master" branch.
When I call it to pull with specified name, then it works:
commits = project.commits.list(get_all=True, ref_name='tst')

I am connecting to our local gitlab server and already tried its API - "projects/12345/repository/commits?all=true" it returns all commits from all branches.

Expected Behavior

project.commits.list(get_all=True) returns all commits from all branches

Actual Behavior

project.commits.list(get_all=True) returns commits only from default "master" branch
