This time it wasn't the path length. We need to fix some parts of the
test suite to adopt to the new (dynamic) locations of the test folders.

I knew this, but I was preoccupied.

I can't do anything today, feel free to revert

or fix the test suites that are affected. I myself can think of fixes tomorrow

For now the testsuite is broken with this.
