(Bug 59204) Properties do not unset on page deletion

Clean-up of related subjects to a property has to be done before store data
are modified which means that either run UpdateDispatcherJob before the
deleteSubject() in "online" mode or put both UpdateDispatcherJob and deleteSubject()
in a DeferredSubjectRemovalJob to ensure synchronize execution.
SQlite no such table: unittest_unittest

$db->tableName( $proptable->getName() ) returns unittest_unittest on SQLite
which causes test to fail.
