HAI-1248 Fix document scroll position in forms

[markohaarni]

Description

Fixed problem where form page in hanke form and cable report application form would not be scrolled to top when entering the form or changing form page.

Made it so that window.scrollTo(0, 0) is called whenever URL pathname is changed so this actually fixes possible scroll position problems in each page change, not just forms.

This seems like a pretty heavy-handed solution. Are there no pages where we wouldn't want to scroll to the absolute top?

Like, this makes the page scroll to the top when changing the tabs on the hanke page? Edit: This was caused by my window being too large. There's no scrolling here with a smaller window.

For me it seems like desired behaviour to scroll to top on each page change, but maybe this needs to be confirmed.
