Fix some hacking violations in the quantum tests.

This patch fixes some import sorting and HACKING violations
in the quantum tests.

Quantum client raises Exception which is discouraged by HACKING.
To avoid some of the HACKING violations we set a constant equal to
Exception and use it for the assertions in the tests.  This avoids
the HACKING violations until we can make quantum client throw a
custom exception class instead.
