Prevent too many redirects error when home page URL set to external_urll

Many users naively set the home page URL setting to external_url
(e.g. https://mydomain.com). When an unauthenticated user signs in, this
causes endless redirections. For example, this is occuring:

1. Unauthenticated user attempts to access https://mydomain.com/dashboard
2. Application redirects to the home page URL: https://mydomain.com
3. Repeat step 2

In step 3, ApplicationController should have redirected the user to
https://mydomain.com/users/sign_in. Disabling the redirection if home
page URL is the same as external_url prevents users from messing up.

* Closes https://github.com/gitlabhq/gitlabhq/issues/8843
* Closes #2057

Change plots to bar graphs

Since line plot does not make sense for this kind of plots, change them to bar graphs. Bar graphs are easier to read and they look cool too.

I would like to change commits per author plots to bar graphs too, but code looks too messy to modify.
