[FIX] website_form: Required hidden field is not saved

Issue

	- Install "Website" app
	- Go to "Contact us" page on website
	- Edit Page, then click on submit button to
	  edit form style
	- Alter 'Recipient Email' then save
	- Edit Page and click on submit button

	'Recipient Email' have default value.

Cause

	If a field is required, the default value is set without
	checking if a value is already set.

Solution

	Set current value if available, else default value.
