QAPISchema.lookup_type('FOO') returns a QAPISchemaType when type 'FOO'
exists, else None. It won't return None for built-in types like
'int'.
Since mypy can't see that, it'll complain that we assign the
Optional[QAPISchemaType] returned by .lookup_type() to QAPISchemaType
variables.
Add assertions to help it over the hump.

Yeah, if you like this more, go ahead. I know it works because I did it this way at one point!
Matter of taste and preference etc.
