There's a bug in ActionView#public_methods(false) that makes it not returning
subscription methods. Using #patterns the log subscribed is asked directly for
its supported event names.

This becomes evident when using Lograge with a lower log level where rendering
logs render-time for each template/partial.

Also added ActiveRecord to the mix that is very noisy when using lograge in development.

Using Lograge in development or with a lower log-level will make AR logs to be
printed.

Do you have a reference [to] the bug you mentioned?

Sorry for the delay, I tried to replicate on a fresh app that I could share, but I couldn't. Anyway the app where I'm observing the bug is ruby 2.3.7, rails 5.1, solidus 2.4 and the usual ton of gems.

I can say though that I noticed that the problem is wider, for example I'm seeing messages from ActiveModel::Serializer in production (see screenshot below). So the problem is more widespread and I think would be useful to have a general way of unsubscribing from noisy components, defaulting to the current environment.

NOTE: I'll wait for instructions on how to proceed before fixing the specs and/or revising the PR 👍
