patch applied (testsuite): Track changes in fuzzy-matching in error messages

[Max Bolingbroke]

If the match threshold at which candidates are reported is something
like (length of identifier) `div` 4 then the match threshold for
length-1 identifiers will be 0, so quite naturally no candidates will
be reported.

Cheers,
Max
