LooperExecutorTest now uses Robolectric instead of being instrumentation
test. This allows the test to be run faster and easier.

LooperExecutor is only truly needed in WebSocketChannelClient because of
WebSocketClient from autobanh requiring thread to have a looper. So
LooperExecutor was left there but replaced everywhere else with built-in
singleThreadExecutor/singleThreadScheduledExecutor.
Motivation behind this change is that built-in class behaves better
under testing environment and doesn't require hacky
RobolectricLooperExecutor.

Test is very simple but should test the basic sanity of the class.
Test is implemented as a JUnit test using Robolectric. Also
removed unused imports from TCPChannelClientTest.

This allows connecting between clients without using external servers, which is useful to OEMs if they are working in a network without internet connection. Implementation uses custom AppRTCClient that replaces WebSocketRTCClient if roomId looks like an IP. Instead of a web socket, this class uses direct TCP connection between peers as a signaling channel.
