[attribute] Add "length" attribute to reset() tests

A "length" attribute is causing attr.reset() to fail
[attribute] Fix #1537. Assume state data is an object

Using Y.each() instead of Y.Object.each() failed when state data had a
"length" property
[calendar] Add test case for bug #1540

Test the bug #1540 that the style of the day of the next month
can be selected when you are showing the next month on a calendar.
