Tagged logging does not work

[johnnaegle]

I've initialized my silencer like this:

config.middleware.swap Rails::Rack::Logger, Silencer::Logger, config.log_tags

config.log_tags is [:uuid]

Silencing is done through the X-SILENCE-LOGGER header.

Every page errors out with:

undefined method `collect' for :uuid:Symbol

I'm using rails 4.2 and silencer 1.0.0.rc2
