Giuseppe D'Angelo f0c2c987e3 QBA(V)/QS(V)::lastIndexOf: fix the search of 1-char needles ... When a needle has length 1 (because it's a QChar/char16_t, or because it's a string-like of length 1) then an ad-hoc search algorithm is used. This algorithm had a off-by-one, by not allowing to match at the last position of a haystack (in case `from` was `haystack.size()`). That is inconsistent with the general search of substring needles (and what QByteArray does). Fix that case and amend wrong tests. This in turn unveiled the fact that the algorithm was unable to cope with 0-length haystacks (whops), so fix that as well. Drive-by, add a similar fix for QByteArray. Amends 6cee204d56.
