* Generate a new updateDate with every call
This should fix#7459
Tests need to be updated in another commit.
* Replace STATIC_TIME with datetime object check
Removing the "DATE" argument from the Alexa component's configuration (because it is now dynamically generated) requires this commit's changes to the test cases to check that the updateDate data is a datetime type rather than a specific hardcoded value ('2016-10-10T19:51:42.0Z').
