lib: drop trailing slash for path and folder searches (infix)

This resolves an old bug reported by David Edmondson in 2014. The fix
is only needed for the "boolean" case, as probabilistic / phrase
searching already ignores punctuation.

This fix is only for the infix (xapian provided) query parser.
