"Revert to VAB" when vessel was selected via Launchpad does nothing

[MehJeb]

Hey there, 

Load the game, go to Kerbal Space Center, click on Launchpad, select your previously saved vessel - it appears on Launchpad, now ESC and "Revert to VAB" - this does nothing - so either this menu item should be disabled or (much better) - just proceed to load the VAB scene with this vessel inside (as was in KSP1).
