McdStorage: adjust IdentifyAccount error behaviour

We were ignoring failures if they were NotImplemented or ServiceUnknown,
but thinking about it more, we should probably ignore "most" errors
here: the only errors that should abort the account-creation attempt
are those that indicate that the intended parameters are unusable,
namely InvalidArgument and InvalidHandle (in its secondary role as
"invalid identifier-that-corresponds-to-a-handle").

Also add more debug messages here.
