Consecutive "role=user" contents in history

[scidomino]

What happened?

The docs say the role for each Content object should alternate between user and model. But there are at least two situations where we don't do that.

1. when adding the IDE context.

2. When canceling function call requests.

What did you expect to happen?

We shouldn't do that.
