Setting a dateFormat without the year makes getDate always return the current year

[nfm]

With dateFormat set to 'D dd M', and a date from the previous year selected (eg 1 Jan 2011), getDate will incorrectly return the current year (eg 1 Jan 2012).

This is inconsistent with altField, and makes it impossible to programmatically get the date with correct year from the datepicker.

I believe this still affects 1.8.18, but jsFiddle only currently has 1.8.16.
