Improve: auto hide company profiles without jobs

[flamuren]

### Is your feature request related to a problem? Please describe
When employers post jobs some add a company profile. This is awesome. However when their job is filled or deadline ended the company profile is left on the website but the job is removed, and it piles up with a lot of old employers/companies that is not longer hiring.

Since I use a dedicated page to show the companies with active jobs to help candidates find employers that hires now, it becomes a lot of manual work to check and always update the list. In the backend its kind of messy since I let their company profile be kept on the website but as "waiting for approval" (but in swedish - not sure the exact translation) if they want to reuse the company profile in the future.

### Describe the solution you'd like
I would like a feature to autohide company profiles if they dont have any active jobs as a setting in admin backend.

### Describe alternatives you've considered
Non I can think of. A simple autohide is all that is needed. Css hide, or filter solution? As easy as possible really.

### Additional context
Let me know if needed.
