ClassCastException in item overview

[Nicklas Nordborg]

Got this error when clicking on "Validate" in item overview for a sample.

class net.sf.basedb.core.RawBioAssay cannot be cast to 
  class net.sf.basedb.core.Subtypable (net.sf.basedb.core.RawBioAssay 
  and net.sf.basedb.core.Subtypable are in unnamed module of loader 
  org.apache.catalina.loader.ParallelWebappClassLoader @4fe9f4ca)

Fixes #2221: ClassCastException in item overview

There was a bug that didn't check if an item (such as RawBioAssay) could be cast to a Subtypable item. The same bug was present also in the protocol and hardware validators and has been fixed there as well.
