check --repair: fix malfunctioning validator, fixes #3444

the major problem was the ('path' in item) expression.
the dict has bytes-typed keys there, so it never succeeded as it
looked for a str key. this is a 1.1 regression, 1.0 was fine.

the dict -> StableDict change is just for being more specific,
the check triggered correctly as StableDict subclasses dict,
it was just a bit too general.

(cherry picked from commit e09892caec)
