[FIX] core: SSF should re-read from the record after saving

Before this change, the SSF would read from the record after
creation but wouldn't do so after a write.

This doesn't conform to the behaviour of the web client (which does a
read() after saving a form), and means the effect of field
inverses (when the dependencies of a writable field are also in the
form) or overrides to write wouldn't be visible afterwards.

It's always possible to just re-create the form from scratch, but the
intention has always been that the form would work correctly after a
save.
