Avoid retain cycle caused by WKUserContentController retaining its message
handler
### Platforms affected
iOS
### What does this PR do?
This PR breaks the retain cycle caused by WKUserContentController retaining
its message handler. This retain cycle would cause apps that create different
CDVViewController instances to leak memory. For instance if you have a
navigation controller, and you push a CDVViewController instance and then you
go back, the view controller just pulled out of the stack is not deallocated.
### What testing has been done on this change?
I tested that the message from javascript are still passed. I think it's
enough.
