Redirect fix breaks redirect

[m-stolle]

What did you do?

Update 1.6.3 to 1.7.0

What did you expect to see?

https://server/prometheus opens prometheus

What did you see instead?

https://server/prometheus redirects to https://server/prometheus/prometheus/graph

Environment

• System information:

Linux 3.10.0-514.16.1.el7.x86_64 x86_64

• Prometheus version:

prometheus, version 1.7.0 (branch: master, revision: bfa37c8ee39d11078662dce16c162a61dccf616c)
  build user:       root@7a6329cc02bb
  build date:       20170607-09:43:48
  go version:       go1.8.3

• Prometheus call:

-config.file=/etc/prometheus/prometheus.yml -web.listen-address=127.0.0.1:9090 -web.external-url=https://server/prometheus -alertmanager.url=http://127.0.0.1:9093/alertmanager -storage.local.path=/var/lib/prometheus/

• httpd.conf:

ProxyPass         /prometheus  http://localhost:9090/prometheus nocanon
ProxyPassReverse  /prometheus  http://localhost:9090/prometheus

I think #2755 is responsible for the new behaviour. I already set the option web.route-prefix=/ but it does not help.
