Always show topic history
I introduced this bug in I8b440d1c7f3e8f1324bdbdce34d64b191b0f93fa
Apparently, if there is no pagination, there won't be any navbar
(so not just in case of error)
The current if-block will cause all of history to be hidden if there
is no pagination.
Meanwhile also added the partial to render errors in board history.
