when making errors in declarations

[samsmith]

On the form submission at /declare/, if the page is shown due to data entry failing validation checks, do not run the "hide the form" javascript at the bottom of the page

if PharmaBenefits.errors or PharmaBenefits.non_form_errors or Declaration.errors or Declaration.non_form_errors

It's trivial enough not to do this if there are form errors in any of those forms.
There's probably a more elegant design than this but for now, sure let's do that.

This form is going to be completely rewritten - leaving open for now to remember not to make the same mistake, but probably not worth fixing for the current form.
