Gabor Apati-Nagy 2e8e7afb7e CA-188554: XenCenter Error Uncaught exception System.NullReferenceException
Fixed the exception that was caused by a missing null reference check and also the fact that the license status had to be watched only for pools and hosts, so added a check before starting watching the license status of the IXenObject (on GeneralTabPage)
