Stuck in product overview

[MaikoCheng]

When pressing the "X" in the product overview when clicking the product, the window does not close. This is at least the case for C1164 but also for other contracts. Link: https://parelpracht.gewis.nl/contract/1164/product/3357#products

This happens because clicking the "X" button actually goes back one page in the browser's history. If you visit this link directly (e.g. by opening it in a new tab), there is nothing to go back to. It is something to take a closer look at how this can be fixed.

When moving some parts to functional components, I noticed that some of the modals are not very "reusable". To fix that issue with this one together, we can supply a close function that does not go back, but navigates back to the correct page instead.
