Directly linking to vacancies is broken

### One-sentence description

When clicking a vacancy and copy-pasting the link, the resulting page does not show the actual vacancy.

### Current behaviour

Copy-pasting a link to a vacancy causes you to navigate to a seemingly random part of the page. This is probably due to the Javascript loading quite late. I realize this is perhaps non-trivial to fix, but that's Javascript for you.

### Expected behaviour

Copy-pasting a link to a vacancy causes you to navigate to the correct uncollapsed vacancy. Perhaps this can be more easily achieved by passing a server-sided CSS class when a page with an anchor is requested.

### Steps to reproduce

1. Go to e.g. https://thalia.nu/career/vacancies#vacancy-41
2. Land randomly on the page rather than seeing the correct uncollapsed vacancy
