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

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

ref:extensions/dune-codegen The unstructured stuff changed the implementation
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!
