docs: Loads the children fo a field annotated with {@link io.neba.api.annotations.Children}.
  Resolves the parent who's children are to be loaded (this might e.g. be a {@link io.neba.api.annotations.Reference referenced} resource).
  Loads all children of the respective parent resource, {@link #convert(org.apache.sling.api.resource.Resource, Class) adapts}
  them if required, and adds them to a newly create collection compatible to the
  {@link io.neba.core.resourcemodels.metadata.MappedFieldMetaData#getType() field type}, if the adaptation result is not
  <code>null</code>.
  
  @return never null but rather an empty collection.
