Create a test case that detects NPE when you create a Run/Debug Configuration

[turkeylurkey]

This test case will detect the issue reported in issue #1202

First open a project and ensure the Liberty dashboard or Explorer has never been opened. We also need to ensure this project has never been opened since the current instance of IntelliJ started. E.g. start IntelliJ, open project X, do some tests, close project X, open project X for some other testing like this test.

With the Liberty dashboard closed, open Edit Configurations... action to edit the Run/Debug configurations. This will cause a Null Pointer Exception recorded in the IntelliJ log. If this happens then fail the test.
