bug(datepicker): Datepicker control is marked as dirty

[rastr5189]

Bug description:

Datepicker control is initially marked as dirty.

Link to minimally-working plunker that reproduces the issue:

I was not able create plunker (becouse of other errors), but you can check this behavior in documentation of datepicker control - https://edcarroll.github.io/ng2-semantic-ui/#/modules/datepicker

datepicker controls has ng-dirty instead of ng-pristine class.

Version of Angular, ng2-semantic-ui, and Semantic UI:

Angular: latest / current
ng2-semantic-ui: latest / current
Semantic UI: latest / current

ng2-semantic-ui - Datepicker control is initially marked as dirty. Making it pristine using Angular's Lifecycle hooks also didn't solves the problem.Bug fix is required.
