DatePicker no default value and misses months for future "max" year on 1st drop down

[trakhimenok]

Ionic version: (check one with "x")
[x] 2.x

I'm submitting a ... (check one with "x")
[x] bug report
[x] feature request

Current behavior:

If max attribute specified into future for example "2020-12-31" the date picker would display:

• Day: {1}
• Month: {unselected but list starts with today's month, currently March}
• Year - {the max one, for this example 2020}.

If I scroll the year to 2019 and back to 2020 all 12 months are shown as expected.

Expected behavior:

Regards bug: I expect either max year with all 12 months (or up to the last allowed by max) or a current year to be selected by default (or first allowed by min property)

Regards feature request: I suggest we have additional property defaultValue.

Reasoning: I want some of my date fields to be optional so I can't fill the value before the picker clicked but once user opens drop down I want a specific date to be preselected, specifically I need today or tomorrow but could be any arbitrary date. Also for optional fields would be nice to have some way to clear the field from previously entered value.

			  max="2020-12-31"
			  ></ion-datetime>
    </ion-item>
  </ion-list>

Looks like a partial dupe of 9846 to me.
