Make the output of the constraints tests readable

In parametrized tests, the failed runs output parameters. In order
for them to be meaningfull for human, the parameter types should be
provided with function that converts them to strings. This adds
these functions for t_pbc and ConstraintsTestSystem types in
constraints tests.
