bug#33782: 27.0.50; Emacsclient ignores errors when its frame is deleted

[Philipp]

Assuming an Emacs server is running:

$ emacsclient --create-frame --eval '(unwind-protect (error "foo") 
(delete-frame))' ; echo $?
0

This means that if the frame created by Emacsclient is deleted, errors
are ignored.  This seems like a bug; I wouldn't expect errors to be
ignored in this case, because they should bubble up through the
`unwind-protect' form.
