Don't highlight version as outdated if it is the same as custom default branch

[kmike]

In Scrapy default branch is set to 0.22: http://doc.scrapy.org/en/latest/

There is also an explicit 0.22 version from the same branch: http://doc.scrapy.org/en/0.22/ - it is highlighted as outdated.

I can just remove 0.22 from visible versions, but I think it is good to have URLs with explicit version number - links can become outdated otherwise.

Looks like it is outdated and it is not possible to trigger a build, trying to force a build on 0.22 updates "latest" branch instead, leaving docs at http://doc.scrapy.org/en/0.22/ outdated.

this urls should serve the same content but they doesn't:

• http://doc.scrapy.org/en/0.22/topics/ubuntu.html
• http://doc.scrapy.org/en/latest/topics/ubuntu.html

I believe this should be fixed with our updates to this logic -- please let me know if it is still an issue, and I will re-open.
