Always store errors details information with symbols.
When the association is autosaved we were storing the details with string keys. This was creating inconsistency with other details that are added using the
Errors#add
method. It was also inconsistent with theErrors#messages
storage.To fix this inconsistency we are always storing with symbols. This will cause a small breaking change because in those cases the details could be accessed as strings keys but now it can not.
Fix #26499.

Remove text default treated as an empty string in non-strict mode for consistency with other types.
Strict mode controls how MySQL handles invalid or missing values in data-change statements such as INSERT or UPDATE. If strict mode is not in effect, MySQL inserts adjusted values for invalid or missing values and produces warnings.
