Removed health check in combination with load-server-state-from-file (Bug) (no replies)

Hi

I run haproxy with 'load-server-state-from-file'. Before reloading
haproxy I dump the state using:

echo show servers state |nc -U admin.sock > /etc/haproxy/state/global

I noticed a buggy behaviour with this:

1. Check that the backend is 'DOWN'.
2. Dump the state using the command above (the 'DOWN' state is written
into the file).
3. Remove the health check of the backend.
4. Reload haproxy.
5. The backend will now be 'DOWN' forever, as the initial state taken
from the file is 'DOWN' and no health checks are running.

I attached an example configuration and an example state file. To
reproduce the issue:

1. Start haproxy.
2. Open the Stats page.
3. Place the state file.
4. Remove the 'check' from the configuration.
5. Reload haproxy.
6. Start the backend.
7. Reload the Stats page and notice that the backend still is 'DOWN'.
