module manager tries to download already downloaded modules
After downloading a module, that module should be removed from the "available modules" list. If a user tries to download the same module twice, there is an NPE thrown.

Modules that are retrieved are not removed from the available modules pane. Instead, they are added to the "Downloaded Modules" list available in the "Downloaded Modules" tab.
I have modified the code to catch a class cast exception that occurred when retrieval occurred before all suites have been calculated.
After this change upon testing, there was NPE when a module was attempted to be retrieved twice.
