extend magic copy test to all scope exit types

Commit v5.15.6-387-g6f48390 forced leavesub to copy returned items
if they were get-magical. Normally rvalue subs  are supposed to return a
copy of their return args, but that copy is sometimes skipped if leavesub
thinks the side-effects will never be visible. Tied elements was an
example where the implementation leaked.

However, this applies equally well to other leave types, such as
do { ....}, so test for get magic in those too.
