Between the find() == 0 obfuscation (since fixed) and this unchecked
replace(), it took me way too much time to figure out what was going
on: the key passed has been invalidated by the setCacheLimit(0).
Now that we QVERIFY that the replace() _fails_, it's much easier to
backtrack and figure out why it does so and why, consequently, the
following find() is also expected to fail.
As a drive-by, reorder two lines so the grouping becomes clearer
(blocks now both headed by setCacheLimit()).
Pick-to: 6.6 6.5 6.2 5.15
