Add missing (require 'ert) for ert-deftest

[andersk]

Although the ert-deftest macro is autoloaded, the ert-set-test function used in its expansion is not, leading to Lisp error: (void-function ert-set-test) when using byte-compiled configs.

That would fix the immediate problem, but would slow down loading the package. I think it's better to extract the tests instead as done in #1819.

Thanks for looking into that @andersk !

I will close this PR since the problem should be solved by #1819

Just to understand: because Melpa tracks Merlin main branch the package is currently broken ? If so I will try to merge the patch quickly to fix it. We still need to understand why the test doesn't pass on Emacs <= 28...

Indeed.

Closing this one in favor of #1827
