Entities nested in a Type Member definition are *not* traversed, beca…

…use the Eclipse Java Outline that we currently

use does not handle members defined in a {{{ org.eclipse.jdt.internal.core.SourceField }}} (which is the data structure
we use to expose type members definition to JDT).

For instance, the following is not correctly handled by the Outline when you click on the nested member `a`:

    {{{type AkkaConfig = a.type forSome { val a: AnyRef }.

Hence, for safety, currently it is better to skip all children altogether. Fix #1000748.
