BUG/MINOR: sample: Make sure to return stable IDs in the unique-id fetch

Previously when the `unique-id-format` contained non-deterministic parts,
such as the `uuid` fetch each use of the `unique-id` fetch would generate
a new unique ID, replacing the old one. The following configuration shows
the error:

  global
        log stdout format short daemon

  listen test
        log global
        log-format "%ID"
        unique-id-format %{+X}o\ TEST-%[uuid]

        mode http
        bind *:8080
        http-response set-header A %[unique-id]
        http-response set-header B %[unique-id]
        server example example.com:80

Without the patch the contents of the `A` and `B` response header would
differ.

This bug was introduced in commit f4011ddcf5b41284d2b137e84c25f2d1264ce458,
which was first released with HAProxy 1.7-dev3.

This fix should be backported to HAProxy 1.7+.
