React-day-picker: DayPickerInput Update From New Props

[kradical]

Hello,

First of all thank you for maintaining this project! It has saved me a lot of time :).

I am currently using it in an app that uses redux-form everything works awesome except when the props get updated the logic of DayPickerInput.componentWillReceiveProps relies on state rather than props.

I will open up a PR and link it here. I believe I have a good fix.

🐛 If you are reporting a bug, show us how to reproduce it here:

• type in 01/01/2009

No update of the DayPickerInput.

I think it is in 6.1.1, Inspecting the code for tag 6.1.1 it seems to be. And I updated to 6.1.1 and could remove my hacky workaround! Cheers!
