Remember flows (#4533)

* Add Konsist test to ensure that the result of a function returning a flow is remembered.

* Remember flows before they are collected by state.

* Fix compilation issue

* Make isOnline a val.

* Make selectedUsers() a val.

* Make flow() a val.

* Make getUserConsent(), didAskUserConsent() and getAnalyticsId() some val.

* Remove Timeline.paginationStatus() and replace by direct access to the underlined flow.

* Simplify test

* userConsentFlow must be initialized before because it's used in observeUserConsent

* Fix test compilation
