New redirects should not be counted as new articles in course statistics

Replica returns this data now, as page_is_redirect.

Next steps:

• add a redirect column to Article
• in ArticleImporter and ArticleStatusManager, set redirect attribute to true for redirects.
• update the ArticlesCourses-related tcode to pay attention to whether an article is a redirect, and don't create ArticlesCourses records in such cases.
• add tests demonstrating that redirects do not count towards number of articles created, number of articles edited, for number of bytes added for courses.

@ragesoss Do we still need to do this?

@ragesoss do we still need to work on this? I find it interesting and would love to work on it

[ragesoss]

@MDCODE247 it is still a relevant issue, but I am somewhat worried about the migration process, which will need to operate on the very large Articles tab. Tackling this will require some testing in a realistic server environment with a large database. As such, I'm going to remove the 'newcomer friendly', and I don't think it makes a good issue for you to start with.

[MDCODE247]

Alright. That's fine.
