Previously, every AppKit tests used the same sharedApplication. Due to this implementation, a could not pass because a previous test made failed the current test. For instance, a test could fail because the window of the previous test resigned (just imagine a new window is the key window in the current test), and this resign could raise an error. The error was displayed for the current test thought this test was perfect !
We now instead of using sharedApplication create a new CPApplication per unit-test file in the class method setUp.
Previously when a menu item was instantiated outside of the context of the menu itself, its highlight state was maintained even after it was removed from the menu. If the menu was dismissed with the item highlighted, and then the item was used in another menu (e.g., re-added to a context menu for a table row) it would appear highlighted, even though the menu highlight index was not set.
This commit ensures that when removing items from a menu that the highlight state of the underlying view is set to NO as well.
Tests for this behaviour are included as well.
Fixes#1899
