checksession iframe stops after first run

Steps to reproduce the behavior

- in config set startCheckSession: true
- use session management OpenID Connect, we use OpenIddict server so for example: https://github.com/GREsau/openiddict-session-management-sample/
- register for EventTypes.CheckSessionReceived notification

I notice that it only fires once at app startup and does not perform any polling afterward.

A clear and concise description of what you expected to happen.

I expect the iframe to continuously poll the session state until either the user logs off from the other app or the session ends.

Additional context

I was curious, so I explored the code for the feature and found a condition in check-session.service.ts that is true only once, and then interrupts the recursion:

angular-auth-oidc-client/projects/angular-auth-oidc-client/src/lib/iframe/check-session.service.ts

Line 97 in 6fcacb4

if (this.lastIFrameRefresh + this.iframeRefreshInterval > Date.now()) {

Additionally, when this condition is true, returning of() stops the Observable in 'pollServerSessionRecur'. I believe that, based on the variable name 'iframeRefreshInterval', the iframe should be refreshed after the default interval of 60 seconds; otherwise, the loop should continue.
