fix(sync): process document state from push response

Do not process document state from create response.
During create the editor has not been initialized fully
and the cursor position is 0 - which is invalid
as it is not inside a node with inline content.
(It is inside the doc before the initial paragraph.)

This also allows processing document state later on
in order to recover from out of sync situations.
But we do not make use of that yet.
