PdfDocument: resolve the source URL

Similar to qtdeclarative 0a1e4cc7ec7548f6273befff9cdddb0bc7a58961
except here, setting the source calls QPdfDocument::load() immediately,
so we need to resolve the URL right before doing that.

The results are visible in most of the manual tests: they again load
test.pdf immediately, as in Qt 5.

Pick-to: 6.3
