Order History - View All Orders for users with OrderReader

[crhistianramirez]

As a buyer user with elevated roles (OrderReader) I'd like to be able to browse orders from any user in the organization.

Acceptance Criteria:

• I should be able to see all orders in an org
• I should not be able to favorite orders that are not mine

Technical Notes - I believe this will involve checking the current user's token. Lets make a general method in a service that takes in the name of a role and returns true or false if the current user has that role.
