Groups from the group page should be clickable to go back to the group list page.
Steps to Reproduce:
Go to the zanata home.
Click on dashboard.
Click on Groups on middle top of the page.
You will see the list of groups.
Click on any group.
There is no such option to go back to the groups list.
Groups shown on top left corner should be clickable to go back to the groups list.
It should be good for each page where we need this type of selection to go back.
