discussed with @ryanml in slack and we decided to remove the context menu item when the bookmark doesn't have a protocol because the ledger info key requires a protocol. i guess the importance of this depends on how many users enter a URL without a protocol as a bookmark.

Per comment from @diracdeltas, I'm going to remove the milestone from this issue. Unfortunately, there isn't a clean way to solve this without resolving the bookmark

sounds good, thanks @diracdeltas and @bsclifton
