Fix old style cast in bindings and retry sanitizer test
Currently, there is an issue with the sanitizer test, for instance in dune/gdt/operators/bilinear-form.hh
which is why it is added to the blacklist. Locally I have seen an "use of old-style cast" warning which @r_milk01 claimed to be related to the test fail. Once this is fixed, we should retry to remove it from the blacklist.
