Datepicker minDate - error is raised when date is exactly min date

Bug

What is the expected behavior?

When minDate is set for the datePicker, a mdDatepickerMin error should be raised only if the date is earlier than the minDate.

What is the current behavior?

For the moment, when setting minDate, the date for exactly min date is NOT unselectable, which means you can select it, but it nevertheless raises an error. I think it should be either unselectable and raise an error or selectable and not raise the error.

What are the steps to reproduce?

Set up a minDate restiriction for the datepicker and try to select the exact min date, and check the fact that it raises an error while it is still selectable.

Angular 4, Material 2

Is there anything else we should know?
