Swipe to next month doesn't work

[danielsilva]

The user is unable to navigate to the next month in the following scenario:

<paper-date-picker
    date="November 1, 2016"
    max-date="February 28, 2017">
</paper-date-picker>

(I tried to create a plunker using your template but the version of paper-date-picker there is 1.1.3)

This is a simple fix for a bug that impedes the usage of the max-date property in specific cases.
I would appreciate it if you could accept the pull request.

I cannot reproduce this either against latest, is this still an issue for you @danielsilva?
