testERP5TestNode: make tests properly isolated

Some tests where patching SlapOSControler to replace methods by a no-op,
but this was never reset. I believe we should rewrite this using mock
which takes care of un-doing the patches for us and makes this testing
easier, but for now I'm just reseting the missing methods like all
others were already reseted.
