Describe the bug
PR #934 breaks git checkout

reproduce
git clone --recurse-submodules https://github.com/jamulussoftware/jamulus >>> FAIL
git clone --recurse-submodules [email protected]:jamulussoftware/jamulus.git >>> FAIL

This is mandatory for github autobuilds (#978), but slipped in Auto-Checks because those do not yet use submodules.
