tdf#91293: Preserve hyperlink on URL field OOXML export

The fix is twofold:
1.Get URL property from the underlying text field, not from the
text run -- put text field properties into rXPropSet (that's
what GETA macro later queries), not into rRun

6a043e9c0acff20e1618ca8ec15c21d5d0fd0d37 does s/rXPropSet/rRun/
afaics for no good reason

2. Retrieve string content from URL field early, so that the test
for empty text content doesn't fire
