Fix ParsingException::displayText()

Browse Source 
Before it was silently try-catched for messages with additional {}, and
it is very easy to trigger, i.e.:

    SELECT toDateTime(format('{}-{}-01 00:00:00', '2021', '1'))

Will print:

    Code: 41. DB::Exception: Received from localhost:9000. DB::Exception: Cannot parse datetime 2021-1-01 00:00:00{}: Cannot parse DateTime from String: while executing 'FUNCTION toDateTime(format('{}-{}-01 00:00:00', '2021', '1') :: 3) -> toDateTime(format('{}-{}-01 00:00:00', '2021', '1')) DateTime : 2'.
