Gábor Antal 75a58a6dd8 Use more specific asserts in test/unit/proxy tests
I changed asserts with more specific assert methods.
e.g.: from assertTrue(sth == None) to assertIsNone(*) or
assertTrue(isinstance(inst, type)) to assertIsInstace(inst, type)
or assertTrue(not sth) to assertFalse(sth).

The code gets more readable, and a better description will be shown on fail.
