bots: De-duplicate removing at-mention pattern for calling bots.

Browse Source 
Similar code appeared at two places (the code is meant to remove the
leading @-mention before passing the remainder of the message to the
bot handler)—both 'zerver/worker/queue_processors.py' and
'api/bots_api/bot_lib.py'.

Remove function from the queue_processors.py file and let the entire message
be processed (includes removing of @-mention) at bot_lib.py.
