RhodeCode CE/EE

The test test_compare_remote_with_different_commit_indexes has an assertion for the len of commit_ids which does not work with git. Since the rest of the test works fine, I've bypassed git in this section (see commit linked below) but this could use some investigation and if possible, make them the same.

I'd guess that the difference here is how the commit history is read by git vs hg when a branch is involved.
