Better logging messages

[aalmiray]

BintrayPlugin has a series of logging statements such as Publication {} not found in project.. It's frustrating to see this type of messages in a multi-project setup with excluded artifacts, i.e, some projects do not expose artifacts (think documentation subproject). It would be better if the resolved project name be used in the message too.

This affects the Griffon setup (more than 34 subprojects) where there are at least 14 projects that do not generate jars that must be published.
