GPII-547: Created "accountCreated" in GPIISession.
The PMT frame hooks to this event to show user token notification.
Made the login/logout calls of GPIISession non-async because we want to serially streamline the logout/login that is triggered by the GPIIStore "refresh" of system level applications when setting preferences. Does not affect much the Ux (at least when running GPII in localhost).
In GPIIStore, when saving preferences of existing user, thus NOT creating new user token, log the user out and then immediately login again in order to "refresh" the system-level applications with the new saved preferences.
GPII-547: Removed the "args" property whenever it contained only {arguments}.
GPII-547: Corrected some comments.
GPII-547: Refresh of AT applications is happening with an event.
GPII-547: Created some TODOs.
GPII-547: Moved logic of success event of set to external function.
GPII-547: Getting logged user's token from GPII.

GPII-547: Added a TODO.
Related to whether we will query GPII every time a component needs to know about the currently logged user or have GPIISession caching it and getting it from there.
GPII-547: Also created a JIRA for the TODO.
