[Automation] docker bats fetch is failing

[v1v]

 make -C .ci/docker test-codecov 
Cloning bats-core
Fetching origin
Reset branch 'v1.1.0'
Clonning bats-assert
Fetching origin
Fetching upstream
Fetching kuisathaverat
fatal: reference is not a tree: 9f88b4207da750093baabc4e3f41bf68f0dd3630
make: *** [bats-assert] Error 128

Not sure whether that's related to my current environment but if I'm able to fetch without errors:

git fetch --all
Fetching origin
Fetching upstream
Fetching kuisathaverat

Not sure if the makefile section regarding the prepare-environment could be simplified with the git submodules as used to be previously, even though there were genuine reasons to move away.

[v1v]

I don't think this is the case anymore
