QQmlError::toString: improve handling of empty urls.

"file::2:23: ..." is strange to read. Show "<Unknown File>:2:23: ..." instead,
by treating empty urls (including "file:") as unknown, and by still showing
line and column numbers in such a case.

This change makes it possible for QUrl::fromLocalFile("") to return an
empty url rather than "file:", which this module was relying upon in the tests.
