With this change, there is a separate subfolder in "test/integration"
for each domain, and each subfolder has its own "test_all.dart".
This change is almost entirely code motion. The only material change
is that two tests have been dropped:
- test_connected(): this test is now unnecessary since every time the
"server.connected" message is received, the generated code in
integration_test_methods.dart verifies that it is well-formed.
- test_error(): this was a placeholder to remind us to test the
"server.error" notification. On further reflection, it's unlikely
that we'll be able to integration test this notification, since it
only occurs in the event of a server bug.
