tests: stabilize for recent wcache changes

This goes with 47e3f554df35::d5622dfe4ba3.  I'm not sure if it was really
expected that there would be no wcache directory if neither execbit nor symlink
is supported.

Test that branchheads cache is updated correctly when doing a strip in which
the parent of the ancestor node to be stripped does not become a head and also,
the parent of a node that is a child of the node stripped becomes a head (node
3). The code is now much simpler and we could just test a simpler scenario
We keep it the test this way in case new complexity is injected.
