redirector.silence_sql_logs = true change log level to 3 in production

[ivan-mr]

Configuring the app like it sais in README.md, in production environment initialized with log level to 1 (:info), sometimes the app changes the log level to 3 (:error).

I detect that making some simultaneous in ajax petitions on the app generates this error. To return the log level to :info I have to restart the app to get the setting initialization.
The error is produced inside class Responder from Middleware, in with_optional_silencing method

To get by with the error, I configured de redirector.silence_sql_logs to true only in development environment. I don't know why still works in development, but in this environment doesn't change.
In production if silence_sql_logs is set to false and logger level is initialized to 3 (:info) the redirector sql logs aren't showed (that is what I want).
