Fix failing InlineEditorProvider tests

There is a good chance that the test doesn't find the Popup message, because of a race condition.
This fix will wait (5 secs) to let the Popup message appear.
In the jasmine source it's says 5 seconds.

    /**
     * Default timeout interval in milliseconds for waitsFor() blocks.
     */
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 5000;
