<Esc> should cancel duplicate

[Hildo Guillardi Júnior]

<Ctrl>+d now duplicated a selected circuit. <Esc> should cancel, instead, it's crashing Eeschema.

@Hildo, can you give specific steps? There have been some changes here so it might be fixed, but I never reproduced it so I'm not sure....

It was simple <ctrl>+d in some block. The <esc> wasn't cancelling.
But in t today's Nightly "6.0.0-unknown-589a37b~86~ubuntu16.04.1, release build" it's fine.
