Make generated test work even when using virtual attributes

The virtual attributes(`attachment` and `rich_text`) can't set value
with `fill_in`. So avoid using it. Once #35885 is merged, will be
modified to use it.

Also, add checking attachment attached or not for avoiding
`DelegationError` when attachment didn't attach.
