Fix `signal` calls where the data argument is not a list

* test/src/thread-tests.el (threads-join-error):
* test/src/emacs-module-resources/mod-test.c (Fmod_test_signal):
* src/print.c (print_bind_overrides):
* lisp/url/url-future.el (url-future-finish, url-future-errored)
(url-future-call, url-future-cancel): Make sure signal's data is a list.

* test/src/emacs-module-tests.el (mod-test-non-local-exit-signal-test):
Adjust accordingly.
