Bug - Keyboard Date Entry Parses YY to 19XX

[patienttruth]

First off, thanks for developing this app. It's quite handy, and intuitive. It actually made approaching Grocy more approachable.

I was doing inventory last night with my son and found a bug, I think. We were entering the dates for some Emergency Food Supply pails which have a shelf life until 2047. When I keyed in 470901 for 2047-09-01, the date 1947-09-01 was entered in. Since there was no way to override with YYYYMMDD I had to make the errant entry and fix it from the Grocy website. Not a big deal, but I'd venture a guess that it's not the intended result.

Anyway, thanks again.
