Fix pom.model properties read for bundle-projects and add it-tests

The TychoBundleMapping tried to look up the buiild.properties of a
'eclipse-plugin' project in its 'META-INF' folder instead of the project
root. This change fixes that.

+ Add extensive integration tests to ensure all pom.model attributes are
correctly read

+ Remove DefaultTychoResolver.setBuildProperties() because its
functionality is already handled by AbstractTychoMapping and it is
currently not working
