The Docker start script variable NIFI_WEB_PROXY_HOST is ignored when using single user authorization

In the Docker start scripts nifi.web.proxy.host is only set when sourcing secure.sh. This only happens when AUTH=tls or AUTH=ldap so the exposed environment variable NIFI_WEB_PROXY_HOST is ignored for the default single user authorization and echoes the following:

NIFI_WEB_PROXY_HOST was set but NiFi is not configured to run in a secure mode. Will not update nifi.web.proxy.host.
