[keycloak-dev] Why does client session expire regardless remember-me extended validity?

IMO single PR is fine. But I suggest to create new JIRA or update 
description of existing JIRA, so that it contains also the description 
for this "new" bug.

2 minor things:
- Is it possible to update this check, so it considers the "min(expired, 
expiredRememberMe)" instead of being hardcoded to expiredRememberMe? In 
most cases, the "ssoSessionMAxLifespanRememberMe" is bigger than 
"ssoSessionMaxLifespan", however it may not be always true. For example, 
someone can want to increase ssoSessionMaxLifespan to some very big 
value, but he doesn't use "remember me", so he won't increase the 
"ssoSessionMAxLifespanRememberMe" .
- Is it possible to add the test for the buggy scenarios? It is hard to 
test it properly, but we somehow test it with usage of time offset and 
manually invoking "expiration check". It is done in 
UserSessionProviderTest - please make sure to use the one from new 
testsuite as this test is currently duplicated in both the new and old 
testsuite :(

WDYT?
