Fix build dependent on core major version

This fixes the build + new test.
I'm leaving a test that only runs for 11.1.x, locally it passes, but we will discontinue soon support for 11.1.x (and it's actually not running in any gitlab ci job)

Looks good to me!

Thank you for keeping the module up to date.

Thanks!
