Updating NI-SWITCH system tests to re-add the enum attribute test

[Fladolcetta]

[x ] This contribution adheres to [CONTRIBUTING.md]

What does this Pull Request accomplish?

Re-adds the system test that was crashing nimi-bot (system test machine).
The system test has been modified to disable reset which worked as a workaround. This appears to be an internal NI-SWITCH bug with DAQmx based devices. Filed as NI internal bug 666018.

Why should this Pull Request be merged?

Fixes #268
Improves test coverage.

What testing has been done?

Ran system tests, verified system test machine test passed

So we don't know why this was crashing in the first place? It just went away on its own?

So from details posted by mimi-bot above:
