KEYCLOAK-3588: DB up-to-date check should not modify DB

Browse source 
The DB up-to-date check uses Liquibase.listUnrunChangeSets() that in
its available variants unconditionally creates a DatabaseChangeLog
tables. Until the variant of listUnrunChangeSets() that suppresses this
behaviour is made public [1] (currently it is protected), workaround
has been implemented that invokes less invasive variant of
listUnrunChangeSets() via reflection.
