fix(handlers): refresh user details on all domains (#1642) 

* fix(handlers): refresh user details on all domains 

* previously sessions only got checked for updated details if the domain had group subjects attached
* this meant disabled or deleted accounts did not get detected until the session expired or the user visited a domain protected by a group subject
* this patch fixes this issue and simplifies some logic surrounding the check

* add tests

simplify IsStringSlicesDifferent so it only iterates once

* add another test for IsStringSlicesDifferent
