Title: Remove unexpected keyword parameter to remove_kernel

Closes gh-3474

I can't now see how to hit this code - the ctypes deliberate crash in our example notebook doesn't hit it, but we were hitting it the other day. There's only one `remove_kernel` method defined in the codebase, and it doesn't have a `now` parameter.
