Fix blank-title validation and its lost form state on re-render

A blank title failed presence and length validation simultaneously,
showing two redundant messages for one problem; length now skips
whenever slug is already blank, matching presence's own skip
condition. Separately, create's failure path never computed
@selected_kind/@parent_id/@parent_name the way new does, so
re-rendering after a validation error silently lost which kind and
parent had been chosen -- for the auto-tagging/auto-templating kinds,
that meant a corrected resubmission could silently produce a plain
generic node instead. required on the title field closes the common
case without a round trip; the server-side fix remains the actual
guarantee, since required is trivially bypassed.
