ResolveMerger: Adding test cases for GITLINK merge

Add test cases which cover content-merge resolve logic.

Git clients try to agressively merge blobs by content, but GITLINK types
of entries can't be merged with each other or with blobs. This change
ensures all possible permutations which can trigger blob and GITLINK
content merge are covered.
