Date and datetime format hint can be incorrect

[Ryan J Ollos]

Noted in comment:4:ticket:12285, the date format hint can sometimes read Try "MMM d, y" or "YYYY-MM-DDThh:mm:ss±hh:mm" instead, but should be Try "MMM d, y" or "YYYY-MM-DD" instead.

I also noticed that when the locale is iso8601 the date and datetime format hint can read Try "YYYY-MM-DD" or "YYYY-MM-DD" instead and Try "YYYY-MM-DDThh:mm:ss±hh:mm" or "YYYY-MM-DDThh:mm:ss±hh:mm" instead, respectively.

Proposed changes in log:rjollos.git:t12295_parse_date_hint:. Tests pass with and without Babel installed.

I guess the issue is similar to [11892].
