* Fixes a duplicate page title on the /videos page
So the `app/views/videos/index.html.erb` was invoking the `#title`
helper method 3 times.
In each invocation the helper method was calling
`content_for(:title) { derived_title }`. Looking at the `content_for`
documentation
[here](9055156668/actionview/lib/action_view/helpers/capture_helper.rb (L117)),
you can find the following comment:
```
Note that <tt>content_for</tt> concatenates (default) the blocks it is given
for a particular identifier in order. For example:
```
Which basically meant that each time the helper got invoked, the title
was appended to the end of the existing title.
This commit fixes the issue by making sure that the `#title` helper is
only invoked once by the view.
