[!307] [bugfix] Fix vectorization with modified quadrature tuple

Merge branch 'bugfix/fix-vectorization-with-modified-qp-tuple' into 'master'

of the parallel key to depend on the quadrature tuple. This means that we need
to make sure that the state of the quadrature tuple is correctly all the time!
