submitGfForm mutation entry returns null even though form gets submitted

Here's a reproducible example for the case: https://codesandbox.io/s/recursing-darkness-xogm66?file=/components/GravityFormsField.js

These seems to be very much an Apollo issue with `useMutation()`. Sorry I can't be more help.

@IlirBajrami apologies. I spoke too soon. On further investigation the issue stems from non-validated users lacking permission to view entries (including their own).
If you're just looking to confirm an entry was submitted successful, ensuring that errors is empty should be enough.

Issue tracking and a temporary workaround until we can ship a solution is happening #222 .
