lvconvert testing is now in its own test, t-lvconvert-mirror-basic ... it doesn't do anything fancy but it does run lvconvert through a lot of combinations. I have also merged the remaining t-mirror-lvconvert tests into t-lvconvert-mirror and abolished the former. The latter will be split again later into more thematic divisions. (The previous split was rather arbitrary, may I even say random...)
