Our version of `go_to()` is very messy, and since we copied it a few years ago, it has been refactored in WordPress.
We can remove the duplication which makes for a cleaner method, and rely on the upstream version.

This also helps avoid false positives in tools that check for use of deprecated WordPress functions.
There was a conditional block in the old `go_to()` that was for compatibility with WordPress <3.9.

Fixes <a href="http://buddypress.trac.wordpress.org/ticket/7326">#7326</a>
