Improve export to CSV functionality

Refactor cell click handler and add more date picker and date range picker tests

Use Chrome Headless browser instead of PhantomJS

Date utility functions `prevMonth` and `nextMonth` change the source
date when using `src.set[Date|Month|FullYear]()`. This change creates a
copy of the date at entrance of function so we have a pure function.

Made some code refactor and added specs for these functions.
