JBIDE-18803 - Bump webservices to version 1.7.1
JBIDE-18714 - Invalid error message when @Target is missing on a custom Name Binding annotation
JBIDE-18392 - JAX-RS Resource wizard: Resource methods are created even though there is no Target entity specified anymore

Fixed the problem by skipping method generation if no target entity was specified
Added a JUnit test to cover that case
