[BUG] - Submit with required fields causing multistep block

[volfkarlo]

Bug explanation

We figured this out by making a mistake while setting up a form on Hubspot.
https://github.com/infinum/eightshift-forms/assets/46056662/6ad54aac-7cad-4635-b81e-fe7886acdb18

We set all the fields to required on Hubspot instead of setting them to "non-required" on Hubspot and required inside the editor.

Afterwards we set conditional logic in Editor and the issue is obvious, Hubspot is rejecting our submission.

But the real issue is not in the setup, but in the inability to do anything(buttons on the form are not working) on the multistep form after submit response.
