Update NetworkAgent#register to compatible with old NetworkAgentTest

aosp/2792436 updated NetworkAgent and NetworkAgentTest.
But the NetworkAgent change was not compatible with the old
NetworkAgentTest.
This CL makes NetworkAgent change to compatible with the old
NetworkAgentTest.

aosp/2851330 will update NetworkAgentTest to support NetworkAgent change
done in aosp/2792436.
Once the old cts is EOL, workaround in NetworkAgentTest and NetworkAgent
can be removed.

Bug: 310124646
Test: atest NetworkAgentTest
