[IMP] web: clear no_create enabled m2o field on focusout

Before this commit: if many2one field has no_create=True and user write
something to many2one field which does not exist and focusout of many2one
field then the text remain there on many2one input field, it creates
consution, it looks new record is created and set, so to avoid this
many2one field should be cleared if there is unmatch string and it has
no_create=True.

After this commit: if many2one has no_create=True and user types string
which does not have any match then on focusout many2one input element
will be cleared.
