Improve TestBlackbox::pathProbe

Add checks for the candidatePaths and the single file API.

Also, this includes a behavior change - if multiple selectors are
present, the filePath/fileName/path probe properties are not set up -
this is because it is not clear how they should be set up in case when
the first file in selectors is found, but the second is not (and thus
probe.found is false). In case of multiple selectors, user should use
probe.allResults but not the single file API.
