Old thread with dash-character can't be opened

[hek]

One of your community members tried to open an old thread with the following title: "Relay actuator sketch - auto off function"

But NodeBB refuses to serve this to the client.

I suspect the url-rewrite gets mocked up but nothing is reported in error/output log.

We're still running v0.7.0-dev something

commit 9165da3b26a044c288d5db73c4933ca2b29e6a78

EDIT: Upgrading to 0.8.2 seems to fix this.
