[min-date] and [max-date] causes unusability

[ukeOnFire]

Please be specific with an example. An issue with no example or unclear requirements may be closed.
Including the min-date or max-date attribute causes the datetimepicker to show only the last row of days and has them all unselectable.
Also, the time is not displayed anymore.

Steps to reproduce and a minimal demo

• include date time picker in html
• set [min-date]='2018-01-01' or [max-date]='someDate'

Current behavior

• no selectable dates at all, time not displayed

Expected/desired behavior

• disable dates lower than value set in [min-date] or higher than value set in [max-date]
• display time
