[server] Fix subscription-based default timeouts

[svenefftinge]

Just surprisingly stumbled over the parallel workspace limit to learn that there were a couple of workspaces running for more than 45 minutes. I'm pretty sure I haven't accessed at least one of them.

Can someone please verify that started workspace where the browser tab idles in the background, actually to time out?

Update: after an hour (I'm on the professional open-source plan) one of the workspaces timed out.
So maybe it is just that the prof open-source account has 1h timeouts (unlike shown in the UI)?

Turns out the default timeouts broke during the migration away from gitpod-com:

gitpod/components/server/ee/src/user/user-service.ts

Line 28 in e8762f2

return "60m";

right now, every user gets a default timeout of 1h.

When fixing this, we must do this in a way that doesn't break self-hosted
