Raises masked AssertionError in _test_network_api
Raises masked AssertionError in _test_network_api

The _test_network_api method was catching an AssertionError to do some
more checking but failed to raise the original error if the checking
didn't hit any matches. This patch fixes the test to raise the original
assertion error.

Closes-Bug: #1212017
