finished CTFs still showing under Import

[lanjelot]

Is this because @lru_cache makes ctftime_fetch_running_ctf_data() return old events at https://github.com/hugsy/ctfpad/blob/master/ctfpad/views/ctfs.py#L33?

[hugsy]

Likely.

But we need some caching here, fetching data from ctftime is a too long operation not to be cached.

[lanjelot]

Can we lower the TTL at all? Or rather what we should do is filter out ctfs that have ended. I'll look into it.

[hugsy]

You can flush the cache but then there's no point.

We can always hide (or add a notation to) the CTF already finished.
