Problematic behaviour in prompt modal #499
Description
The goal is to make the modal more intuitive to use.
If user clicks "Lisää uusi alustus"-button, it disables the tabs, without explanation why.
Fix suggestion, is to always keep tabs enabled, but when tab is changed while in "luo uusi alustus"-mode, it just cancels the prompt creation. In other words, it executes the same functionality as the "peruuta"-button in the picture.
