match: simplify nevermatcher

Most of it does the same as its superclass, so it can simply be
removed. It also seems to make more sense for it to use relative
paths, as we do for everything except alwaysmatcher, although
nevermatcher.uipath() will probably never get called anyway, so it
won't matter.
