Make UBER jar as the default jar (#553)

The build process produces the following artifacts in the target directory:
 - Shaded uber JAR (default): ${project.artifactId}-${project.version}.jar
 - Thin JAR without dependencies: ${project.artifactId}-${project.version}-thin.jar
 - Test JAR containing test classes: ${project.artifactId}-${project.version}-tests.jar
 - Sources JAR (when 'release' profile is active): ${project.artifactId}-${project.version}-sources.jar
 - Javadoc JAR (when 'release' profile is active): ${project.artifactId}-${project.version}-javadoc.jar
