Update logback to the latest version

[mkpaz]

On my PC application doesn't start with logback v1.1.7. Maybe it's because my PC has no DNS configured (I work behind proxy). Maybe it's a logback bug. I don't know. Here is the exception:

Failed to instantiate [ch.qos.logback.classic.LoggerContext]

To fix this problem I need either to delete logback.xml from conf/ dir, or force logback to v1.2.3. Then all works just fine.

Upgrade sounds good.

Run mvn dependencies:tree and check if there is a dependency that fetches a newer version of logback and result in this runtime error.

No, I just began to work on my project, so it's not so different from starter for now.

Since I inherit my pom from jooby-modules it's quite easy to change logback version through overriding property placeholder: <logback-classic.version>1.2.3</logback-classic.version>

I had an older version of logback switching to 1.2.3 fixed the issue.
