ion-datetime issues with properties: min max displayFormat pickerFormat

[ecureuill]

Short description of the problem:

Add displayFormat or pickerFormat attribute led to:

1. miss day column in picker and don't fill the day in display.
2. if pickerFormat is YYYY and displayFormat is not defined, display value show ,YYYY

Add max attribute with a date less than current date lead to

1. Miss month & year column in picker if max attr value less then (current date - 101)
2. Miss month column in picker if max attr value less then current date & greater then (current date - 100)After scroll in picker or select a date, missed column appear.

Add min attribute lead to:

1. Miss month & year column in picker if min attr value greater then current year
2. Miss month column in picker if min attr value is today, yesterday or tomorrow. After scroll in picker or select a date, missed column appear.

What behavior are you expecting?

1. Set any valid format to displayFormat or pickerFormat must not break the component
2. If pickerFormat is defined and displayFormat is not defined, displayFormat should be set to same format as pickerFormat
3. If max attr value is defined, min attr value is not defined and max attr value is less then default minimum value (current date - 100 years), then min value should be set to the year of defined max value attr to avoid issues
4. If in attr value is defined, max attr value is not defined and in attr value is greater then default maximum value (current year), then max value should be set to the year of defined min value attr to avoid issues

@ecureuill Working on this now. The example where it's missing a day, the format for day is uppercase DD, so that's why dd isn't working, and I'd rather not add code which is an alias for the same thing. http://ionicframework.com/docs/v2/api/components/datetime/DateTime/

@adamdbradley do you know if there will be any performance improvements for date picker on android devices? At least on Moto X Pure Marshmallow, date picker rolls glitchy and slow. If you haven't experienced this we may open another issue to work it out. Thanks! :)

@devarg yes, @manucorporat just completed a refactor that addressed many of it's issues. fc2ee64 It'll be in the next release.

Thanks for the help @ecureuill! A few more unit tests were added to fix this bugs, thanks!
