Validate you've turned off all the SocialConnections
I feel for others -- I too would never have added Twitter as an account if I knew that all my Twitter contacts would be added to my phone contacts. What a pain.
All I can suggest is before you try to remove the Twitter account is to first close the default Twitter app itself.
Then go through all the running services and make sure ANYTHING associated with SocialMedia is killed. I remember closing a bunch of services, I don't remember them all. That seemed to do the trick for me.
