Not only is this unnecessary, but worse it changes the assignment's
resource_link_id, messing up any LTI tools that rely on that
parameter.
fixes CNVS-5884
test plan: Create an LTI assignment using any tool, and inspect the html
to view the launch parameters. Record the resource_link_id. Then edit
and save the assignment, and inspect the launch parameters again. The
resource_link_id should remain the same.
