Remove confirmation for opening the merge tool

The confirmation used to make sense back when the Open MergeTool command was its
own top-level command; however, that command was changed in 703f053 to open a
menu instead, and Open MergeTool is now just a submenu entry in that menu, so it
no longer needs a confirmation.
