Timber library got upgraded to version 1.7.0

But we are using the version 1.5.2

Timber had disabled the automatic updates because "The newest versions may break your site, don't do it unless you are willing to fix your code"

https://wordpress.org/plugins/timber-library/

Task: Update timber to the latest version (locally), test that the site works (coordinate with kdiamant about running the test locally and with lreyes for running them once this is on dev.p4).
