Hi, this PR tries to fix two issues with [clone]:

1) prevent a save cloned abstraction from closing (unless you change the inlets/outlets) 2) fix the order of loadbangs within cloned abstractions in relation to the parent canvas.

since this is a bit delicate I'd be happy if more people could test it and report any issues.
