Surprising charm downgrade

Bug Description

I had a model with cs:trusty/haproxy-19 deployed, and proceeded to deploy a bundle that specified cs:trusty/haproxy-10 and other charms.

To my surprise, juju downgraded the haproxy charm from -19 to -10 (console output attached):

$ juju deploy ./bundles.yaml
added charm cs:trusty/haproxy-10
upgraded charm for existing service haproxy (from cs:trusty/haproxy-19 to cs:trusty/haproxy-10)
configuration updated for service haproxy

I think juju should loudly complain about this situation, maybe even refuse to deploy. But not downgrade a charm just like that.
