test_system_nidmm.py test_ViSession_attribute fails

[marcoskirsch]

Test expects session.io_session = 5 to raise TypeError.
This test used to work, although someone could argue that we should allow setting a numeric value on a ViSession.

The reason this now fails is that the io_session went away from metadata. So the line:

session.io_session = 5

is inserting a new attribute into the session instance.

So the test is invalid and I will fix it. But it raises the question of whether we should disallow inserting attributes into the session instance.
