make reauth test compat with tailscale head (#2167)

* make reauth test compat with tailscale head

tailscale/tailscale@1eaad7d broke our reauth test as it makes the client
retry with https/443 if it reconnects within 2 minutes.

This commit fixes this by running the test as a two part,
- with https, to confirm instant reconnect works
- with http, and a 3 min wait, to check that it work without.

The change is not a general consern as headscale in prod is ran
with https.
