[patch] Update chrome driver to support chrome version 58 in tests

Hi Hackers,

With the update to version 58 of chrome the version of the chrome driver of
Selenium need to be updated to version 2.29.

This patch does that change.

Note:
If you had previously installed the old driver you need to uninstall and
install again it.

$ pip uninstall chromedriver_installer
$ pip install -r regression/requirements.txt

​

Thanks
Joao & Oliver
