GH-2805: StreamBridge send and custom content-type

Browse Source 
- When StreamBridge#send is called with binder-name and custom content-type,
   it does not honor the content-type value, but default to application/json.
   Fixing this issue for this call path by explicitly checking for any custom
   content-type provided on the binding.
