Premature Token Expiration

[jheinnic]

Working on trying to integrate the Observable signal sources I've bumped into a bug that's causing my sessions to get closed down right after returning from login.

The problem seems to be in the service handling code that is attempting to use setTimeout( ) in order to schedule a callback to pushTokenExpired( ) at the calculated expiration time. The calculated time seems to be correct, but instead of passing a reference to pushTokenExpired for future callback, the code is calling pushTokenExpired() and scheduling some behavior for whatever it returns.

`this.tokenTimeoutHandle` = setTimeout(this.pushTokenExpired(), expiresIn * 1000);

All that pushTokenExpired() does is fire one of the expiration observables, so I'm reasonably certain that calling it instead of passing it as a reference is a mistake and the intended logic is:

`this.tokenTimeoutHandle` = setTimeout(this.pushTokenExpired, expiresIn * 1000);

A workaround for the moment could be to just ignore the observables for token expiration. The Observables that fire on successful login are separate from those that manage expiration, so I can just disregard the expiration signals for now, but it would be better if they just behaved correctly.
