Follow redirects when notifying users (#322)

Fixes #90

Advantages
- Simpler than patch #291
- The original intent of the function notifyUser was to follow redirects, indicated by the comment "Follows redirects and appends a message to the bottom of the user's talk page." from 2014. So this fixes that bug.

Disadvantages
- Will only follow 1 redirect, not 2+ redirects.
- The "Saved [[User talk:OldUsername]] (diff)" message shown to the AFC reviewer will be slightly incorrect. The diff will be correct, but OldUsername should ideally be NewUsername.
