Bug #19410

If move from ractor fails with error, some objects are left in broken state

Description

r = Ractor.new do
  obj = receive
end
a = Object.new
obj = [a, proc { }]
begin
  r.send(obj, move: true)
rescue => e
  puts "couldn't move"
end
p a # a is moved, this errors out. But it's not really moved because the other ractor can't access it. It's in limbo :)
r << :end
r.take

This might be tricky to fix, as it requires some sort of commit function for moving objects after every object is checked for ability to move.
