Darragh Bailey 47092a9b63 Fix finish merge to ensure correct contents
Make sure to use the same variable for all git commands in the finish
phase as this has already been set to the correct branch or sha1
depending on whether the currently in a rebase or not.

In certain cases the finish steps were not using the correct references
to merge and read-tree resulting in the final merge containing the
wrong tree contents.

Add test to cover the conflict and manual resolve case, as well as
adding a check to the other tests for testing the resulting merge
contains the correct contents.
