datepicker: invalid value on first load from moment

[j-walker23]

Bug Report

Demo URL (required)*: https://datepicker-invalid-value-on-first-load-from-string-12075-pskwl4.stackblitz.io

Detailed Reproduction Steps

1. Start date as moment object

List the affected versions of AngularJS, Material, OS, and browsers

• AngularJS: 1.8.2
• AngularJS Material: 1.2.3
• OS: All
• Browsers: All
• Screen Readers:

Add anything else we should know

This was just fixed for string being the default last version.
I added the below to that ticket, but I added it too late. I should have just opened a new ticket. Sorry about that.

When DatePickerCtrl.prototype.updateErrorState is called with a moment date
if (this.dateUtil.isValidDate(date)) { is false
So this.ngModelCtrl.$setValidity('valid', date == null); runs and the ngModel ctrl valid key is set to false.

Thank you for opening this issue. Sorry that I didn't notice your comment in #12075 and address that as well in PR #12115.

@Splaktar it seems this bug is also present if you use the Luxon Adapter instead of the Moment Adapter

[Splaktar]

@matrium0 AngularJS Material doesn't have an official Luxon adapter. Which are you using?

[matrium0]

Ah sorry, I noticed a similar bug in MatLuxonDateModule (installed via @angular/material-luxon-adapter) for Angular not AngularJS.

My bad! (still I choose to blame it a tiny little bit on the choice to "keep the name" Angular :D ). Thanks for your quick response!
