Bug with VUU Server option for adding customised login validator is not setting

[naleeha]

When using following builder syntax to register the custom login validator, VUU server does not use it but use the default login validator.

VuuSecurityOptions.apply() .withLoginValidator(new MyCustomLoginValidator()),

Issue seem to be a bug in following:

See class VuuSecurityOptionsImpl

override def withLoginValidator(tokenValidator: LoginTokenValidator): VuuSecurityOptions = this.copy(authenticator = authenticator)

It should be using the passed in tokenValidator in the copy it returns.
