Fix custom reply title.

The custom reply title is actually still broken. Previous the latest, the custom title wasn't being applied. Now the custom title is being used but if you use the {title} token the custom title actually replaces the token instead of the topic reply title. For example this:

`Connections :: {title}`

became this:

`Connections :: Connections :: {title}`

I tested this on my live site, so this works for me...
