KAZOO-2144 Typo in cb_faxes.erl

Line 290: 
Timezone = crossbar_util:get_account_timezone(AccountId, OwnerId), 

There is no crossbar_util:get_account_timezone/2 

As a result request fails: 

{"auth_token":"++++++++++++++++++","request_id":"f91e5e8f5c3f2f26839de90a06dc6b88","status":"error","message":"init failed","error":"500"} 

Besides that, common logic says it should be crossbar_util:get_user_timezone(AccountId, OwnerId),
