Bug: plate loading using loadContainerHierarchy doesn't work

[sbesson]

The following error was obtained when trying to call

objectList = proxy.loadContainerHierarchy('omero.model.Plate', ids, parameters);

from Matlab. All the other objects (Project, Dataset, Screen) work as expected.

Java exception occurred:
omero.ApiUsageException
    serverStackTrace = "ome.conditions.ApiUsageException: Class parameter for loadContainerIHierarchy() must be in {Project,Dataset,
    Screen, Plate}, not class ome.model.screen.Plate

No logic seems to be implemented to retrieve plates in
​/ components/server/src/ome/logic/PojosImpl.java.
However Plate is in the list of allowed classes in the error message (and is documented in the Sphinx documentation) which lead to confusion.

Note that the method (not for plate) is already tested in Java.
