Fix property warnings and hide some debug prints

"ALL IS GOOD" was a lie.

In particular, removes verbose "path not recognized" false positive.

The actual logic is to (somewhat naively) check all ResourceFormatLoaders
and to pick the first good match, so no need to warn about the formats
that do not match the type hint.
