Speed up the DHCP roaming tests.

The DHCP roaming tests all call doDhcpRoamingTest. This method
appears to want to have the IpMemoryStore return null, but
instead just causes DhcpClient's IpMemoryStore query to time out.
Fix this by actually calling the onNetworkAttributesRetrieved
callback with null.
