GraphBookmarksUI : Preserve editor links when using the 0-9 hotkeys

The 0-9 hotkeys switch the editor to the specified bookmark. It's more
intuitive for users if this updates the master editor in a linked setup,
rather than replacing the link itself and pinning the editor that received
the shortcut.

User facing changes:

 - Pressing the 0-9 bookmark hotkeys no longer breaks editor links
