Can't open Working set context menus when all the Close Other preferences are false

[TomMalbran]

Open the the user preferences file and add the next 3 lines:

    "closeOthers.above": false,
    "closeOthers.below": false,
    "closeOthers.others": false

After saving the file, try to open the working set context menu.

Result
It doesn't open
Expected
It should still open

There is a second minor issue when you set any of those preferences to false, and restart Brackets. In that case when you open the Developers Console, you should see an error, where the code is trying to remove a menu item that was never added.

Both issues are fixed in PR #7088.

This is now fixed in master. Closing
