AdvancedSecurityDataCollectionFlag is always true

[grmoon]

In lines 74-77 of CognitoAuth.js advancedSecurityDataCollectionFlag is set. This property is a boolean, however it can only ever be set to true due to the conditional before it is set from the AdvancedSecurityDataCollectionFlag passed to the constructor.

this.advancedSecurityDataCollectionFlag = true;
if (AdvancedSecurityDataCollectionFlag) {
    this.advancedSecurityDataCollectionFlag = AdvancedSecurityDataCollectionFlag;
}

These lines should really just be

this.advancedSecurityDataCollectionFlag = Boolean(AdvancedSecurityDataCollectionFlag);
