tests: Use group control interface for GO commands in autogo_chan_switch

The channel switch command is intended for the GO interface, but
it was not sent on the group control interface. For configurations
that use a separate interface for P2P groups, this will fail the test.

Fix this by sending the channel switch command on the group control
interface and waiting for the channel switch event on the group
control interface.
