Damir Jelić 9cd217fc5d matrix-sdk: Remove the proxy usage from the exmaples for now
While it's generally useful to watch what the sdk is sending
out during development using mitmproxy, users of the sdk might
wonder why the example doesn't connect.

Remove the proxy usage until we add a cli parser which can enable proxy
support with a command line switch.
