Bug #31928: Search fails on '1000-00-00' date after sql_mode change

Browse Source 
When constructing a key image stricter date checking (from sql_mode)
should not be enabled, because it will reject invalid dates that the
server would otherwise accept for searching when there's no index.
 
Fixed by disabling strict date checking when constructing a key image.
