Change subject: Fix suspend/resume tests
......................................................................

Fix suspend/resume tests

Ensure that a suspend/resume was sent before sending the *_(N)ACK. In
reality these can only happen together and our TLLI cache removes
the entries after it sees the corresponding (N)ACK so it will not
forward the second message.
