Jonas Jenwald 9f8d9802f9 A couple of small (viewer) tweaks of tooltip-only Annotations (PR 12333 follow-up)
Ensure that these tooltip-only Annotations are handled as "internalLink"s, to ensure that they behave as expected in PresentationMode (e.g. they should still use a `pointer`-cursor).

Ensure that `PDFLinkService.getDestinationHash` won't create links with empty hashes, since those don't really make a lot of sense in general (this improves things for tooltip-only Annotations).
