Fix: Text input schema needs top level answers (fixes #114)

[lemmyadams]

Addresses #114

Fix

• Adds top level _answers property to the schema.

This is particularly important as one of the latest PRs now unconditionally checks for this. [See screenshot]. This now fails because there's no _answers array to retrieve, and you can't perform a slice() method on something undefined

[oliverfoster]

"_answers" is an array of arrays of strings - an array of strings is considered an answer with its aliases and can only be used once in any text input.

Yours:

[
      "Asia",
      "Africa",
      "North America"
]

Configuration:

[
      ["Asia"],
      ["Africa"],
      ["North America","N America", "N. America"],
      ["South America","S America", "S. America"],
      ["Europe"],
      ["Antarctica"],
      ["Australia"]
]

@oliverfoster I've updated it to be an array of strings. I'm unsure on what it should exactly be so let me know if there's anything further needed to change

This needs testing in an AAT now. I was quite sure the it wasn't possible to specify a schema that does this. As per #114 (comment)

@lemmyadams Does this still allow for aliases / alternate spellings? For instance, if the question is "List the names of seven continents", we would not want users to get two correct answers if they enter both "North America" and "N. America" since they are the same continent.

Hi Lemmy, I believe this can be closed off now
