OAuth configuration gets ignored when clientSecret is an empty string

[nlochschmidt]

Because the empty string is a falsey value in JavaScript and the clientSecret is checked in https://github.com/springfox/springfox-swagger-ui-rfc6570/blob/master/src/web/js/springfox.js#L70, the OAuth configuration is ignored when no clientSecret is provided.

This has already been fixed in https://github.com/springfox/springfox (see springfox/springfox#1592)

In my case the OAuth Provider (Keycloak Server) simply ignores client secrets for non-confidential clients so I can put in a random clientSecret as a workaround.
