MDEV-4856 SQL_ERROR_LOG shows 1146 errors which didnt appear in mysql client.

Browse Source 
The fill_schema_table() function used to call get_table_share() for a table name in WHERE
    then clear the error list. That way plugins receive the superfluous error notification if it
    happens in it. Also the problem was that error handler didn't prevent the suppressed
    error message from logging anyway as the logging happens in THD::raise_condition
    before the handler call.
    Trigger_error_handler is remade into Warnings_only_error_handler, so it stores the error
    message in all cases in the thd->stmt_da.
    Then later the stored error is raised.

We do not clear is_fatal_error or is_fatal_sub_stmt_error since we
assume this is never called if the fatal error is set.
