In both the Special:CheckUser and Special:Investigate/Timeline displays, partial blocks from namespaces are all shown as `the namespace Special:AllPages` (with `Special:AllPages` being linked to the special page) rather than saying which namespace is actually being blocked.
I suspect this is because, in the entries in Special:Log, the namespace name is linked to Special:AllPages for that namespace? See `BlockLogFormatter::getMessageParameters`
**Steps to reproduce**
* Block a user from a namespace (e.g. Talk)
* Navigate to Special:Investigate and start an investigation //for the admin who made the block//
* Go to the Timeline tab
* Expected: A log line says that the admin blocked another user "from the namespace Talk"
* Expected: A log line says that the admin blocked another user "from the namespace Special:AllPages"
