Alexander Dupuy 5c752935fd Refactor check-merge-conflicts tests
Do a straight test of detecting a real merge conflict as generated by git.
Test artificial conflict detection while pending merge without a real conflict.
Test artificial non-conflict non-detection in a resolved merge conflict.
Rename test_does_not_care... function to reflect what we want to care about.
Rename is_in_merge_conflict to is_in_merge since that is what it checks.
