branchmap: Add a test about writing branchmap and aborted transaction
It turn out that we update the branchmap on disk whenever we recompute it…
including in a middle of a transaction. This means writing the new branchmap too
early (the changeset are not visible yet) and worse… it mean writing branchmap
for transaction we rollback.
so we introduce a test to highlight the issue (and prevent it to regress in the
future).
