Pass LOG_TIMESTAMPS configuration into the logger instances properly

[courajs]

We check the environment for LOG_TIMESTAMPS configuration:

logger/src/main.js

Line 31 in 87a97a2

timestamps: process.env.LOG_TIMESTAMPS !== 'false'

But, we forget to pass it into the logger instances. We should be doing the same thing that we are for interactive:

logger/src/main.js

Line 20 in 87a97a2

interactive: createLogger.config.interactive,
