[Datepicker] dates/formats are constantly changed upon entering calendar

[konradkukier2]

Is this a bug, enhancement, or feature request?

bug

Briefly describe your proposal.

Entering calendar (either via calendar icon or input) triggers date/format changes.

Note that theres also validation (red border) triggered for some dates, probably because of wrong format (30.06 is considered as 6th day of 30th month)

Which versions of Angular and Fundamental NGX are affected? (If this is a feature request, use current version.)

fundamental-ngx: "0.5.2"
fiori-fundamentals: "1.5.7"

If this is a bug, please provide steps for reproducing it.

Please provide relevant source code if applicable.

                <fd-date-picker
                    [type]="'single'"
                    formControlName="start">
                </fd-date-picker>

    this.form = this.fb.group({
      start: [],
      end: [],
    });

Is there anything else we should know?

@mikerodonnell89 If you remember this is what I had said @JKMarkowski 's closed PR fixed. This is due to us using toLocaleDate, so this all works fine in the US and Canada, but the format is different for some EU countries. This includes Poland and Austria.

Now it's important to note that the closed PR did not truly fix the issue. It made it so that the calendar worked in the EU but not in North America. The real solution is to eventually get rid of the JS date object, but for now we could also probably stop using toLocaleDate and instead use a more reliable format method.
