subtree: fix "git subtree split --rejoin"
"git merge" in v2.9 prevents merging unrelated histories.
"git subtree split --rejoin" creates unrelated histories when
creating a split repo from a raw sub-directory that did not
originate from an invocation of "git subtree add".
Restore the original behavior by passing --allow-unrelated-histories
when merging subtrees. This ensures that the synthetic history
created by "git subtree split" can be merged.
Add a test to ensure that this feature works as advertised.
