It is possible to assign one tag mutipletimes to one bookmark

[pinkavaj]

Right now it is possible to assign the same tag multiple times to the same bookmark. The workflow is a bit obscure, but with many tags in the list not impossible.

Steps to reproduce:

• Open "Bookmarks" tab
• Select "Add new bookmark"
• In the window click "add new bookmark" and set a name
• Do the same again and again with the same name ...

Similar approach can be used for editing tag for existing bookmark

I can't reproduce observed behavior. This does not assign multiple tags. This just creates multiple bookmarks at the same frequency with the same (or different) name and the same or different tags. I think that's a bug too, but a different bug (I've fixed this in my dev branch, but I have not opened a PR yet... Or the fix is buried inside of multi_vfo branch, I don't remember.)

There are at least 2 different solutions:

1. Avoid creating multiple bookmark at the same frequency. Fail silently or with a message.
2. Update the existing bookmark with a new name and tag list (my fix follows this way).
