QTextImageHandler: Add test coverage for resources and URLs

If an image source in HTML is specified via local file name or resource
path (i.e. without qrc prefix), then the correct image is loaded.

With file:/ or qrc:/ schema however, the image is either not loaded at
all, or the 2x image is not loaded. The qt_findAtNxFile helper in
qicon.cpp gets a URL path, but expects a file path (that can be tested
with QFile::exists).
