There are cases where the xa recovery scan is started and never ended ( TMSTARTRSCAN and TMENDRSCAN flag), see discussion in Agroal issue: https://issues.redhat.com/browse/AG-238
Jonathan suggested a fix to solve the issue: see https://github.com/jbosstm/narayana/compare/main...jhalliday:narayana:recover-a
Add also unit test for the change.
