bug fixed and related to the cache. File related to cache removed with the portlet unregistering. Class GWTdbManagerServiceImpl modified adding the method destroy that removes the cache and file encache.xml changed setting the parameter diskPersistent to false value in order to remove the file in temp folder. 

git-svn-id: https://svn.d4science.research-infrastructures.eu/gcube/trunk/portlets/user/databases-manager-portlet@99964 82a268e6-3cf1-43bd-a215-b396298e98cf
