Change isValid to isSubmitted.

[mustafaaloko]

Fixed this line: isValid() returns false if the form was not submitted.
To this: isSubmitted() returns false if the form was not submitted.

👍 @mustafaaloko thanks for this nice catch!

Both isValid() and isSubmitted() return false if the form was not submitted. The extra call is there purely for more clarity. I think it is important to mention that isValid() also returns false when the form was not submitted. However, I also agree with your change: 👍

Should we update the following two items too to make the text more consistent (both refer to isValid() and the wording now doesn't perfectly match anymore with the changes to this item imo)?

Thank you @mustafaaloko! I've merged your changes into the 2.3 branch (I'll merge it to others from there). As suggested by @xabbuh, I've also reworded the next 2 items a little bit in 934aad5. I kept the isValid calls, as they are about validation.
