Fix KeyError , get_profile_media function

Fix instagram_profile_js catch AttributeError , function, instagram_profile_json to return empy json when a ConnectionError occurs

Thanks for the error managing, I'm changing some except blocks, having zero messages on error is never a good idea.

Ok, an other exception is ConnectionResetError(104, 'Connection reset by peer'). In general connection errors occur when instagram is down or maybe when a client connects to the site via mobile phone.
