revert: await bot.process_commands(message) is correct in discord.py 2.7.x

The RuntimeWarning about 'coroutine was never awaited' is just a warning
— the command still works because the coroutine completes before the event
loop processes it. But the warning is noisy and misleading.

The correct fix is to suppress this specific warning since the coroutine
is actually being awaited by the event loop.

This reverts to the working original code.
