Ticket #48212 - Dynamic nsMatchingRule changes had no effect on the attrinfo thus following reindexing, as well.
    
    Description: When nsMatchingRule was dynamically updated in an index entry,
    the value was set to the configuration but was not applied to the attribute
    info.  On-line reindexing following the nsMatchingRule change actually ignored
    the setting. On the other hand, the standalone utility dbverify independently
    picked up the nsMatchingRule from the configuration and generated the attribute
    info, which expected the index reindexed based upon the new nsMatchingRule. But
    it was actually not and dbverify reported the index corruption.
    
    This patch applies the changes to the attribute info when nsMatchingRule is
    modified.
