Bookmarks leaves markers when duplicate entries in an import

[nexushoratio]

Just a minor resilience issue solved by reloading the page.

Import the following that was edited by hand to include the same portal twice. Click on the marker to demonstrate that two markers exist.

Delete one of the bookmark entries. One of the markers stays behind. A page reload resolves.

Depending on which way the entry was deleted (via [x] in the UI box, or ★ in the portal details), other things may get left behind as well, generally also resolved on a page reload.

Obviously, garbage-in/garbage-out, but if someone is bored and wanted to improve it a bit...
