nixos/taskserver/helper: Assert CA existence

We want to make sure that the helper tool won't work if the automatic CA
wasn't properly set up. This not only avoids race conditions if the tool
is started before the actual service is running but it also fails if
something during CA setup has failed so the user can investigate what
went wrong.
