Duplicated and malfunctioning URL for search page

[dxvargas]

Both of these URLs will return the same results:

• http://web:8080/build/search?search_api_fulltext=term
• http://web:8080/build/search/term

... but the later will not have the filter nor sort options displayed in the page.
Maybe it's not really critical but anyway in UCPKN we've avoided this issue, you can see our Pull Request here.

There is another problem when using the Contextual filter. When sorting the results, the searched term is lost.

Both these problems could be avoided using a normal view filter... wouldn't it be a better solution here?
