When writer was set as SHUNNED due to replication lag, and 'mysql_servers' table was regenerated (via servers reconfiguration or other action). SHUNNED writer wasn't considered a found writer, triggering an unwanted server reconfiguration.

…writers' Since servers present in 'backup_writer_hostgroup' where not considered as previously configured writers, everytime the number of available writers exceeded 'max_writers' an unwanted server reconfiguration was triggered for each of these servers at every monitoring action.
