    Summary:
     Verifying logic flow of the "+" button on the Script Canvas pane's Node Palette is as expected

    Expected Behavior:
     Clicking the "+" button and selecting "New Script Event" opens the Asset Editor with a new Script Event asset

    Test Steps:
     1) Open Script Canvas window (Tools > Script Canvas)
     2) Close any existing AssetEditor window
     3) Get the SC window object
     4) Click on New Script Event on Node palette
     5) Verify if Asset Editor opened
     6) Verify if a new asset with Script Canvas category is opened
     7) Close Script Canvas and Asset Editor


    Note:
     - This test file must be called from the Open 3D Engine Editor command terminal
     - Any passed and failed tests are written to the Editor.log file.
        Parsing the file or running a log_monitor are required to observe the test results.
