Test cases were not waiting for page load after clicking.
This caused failures in test cases that were executed right after
these incorrect ones, because of requests hitting server after
a test was finished.
We do not have to click links, we can go directly to a correct page
by passing parameters in the URL.

This allows the test to pass when your local time zone is different
than UTC.
"Date Format" JavaScript library uses a custom, non-standard format
when displaying time zone part of the datetime. There is no point in
trying to replicate this behavior in Ruby.
