[Bug Report] Test of VOverflowBtn not correct

[borisdayma]

Versions and Environment

Vuetify: 2.0.0-alpha.10
Vue: 2.6.10
Browsers: Chrome 73.0.3683.75
OS: Windows 10

Steps to reproduce

Pull request #6797 was merged, however an error was introduced: see line 41 of VOverflowBtn.spec.ts in pull request diff.

Expected Behavior

The test "segmented - should warn when item has no callback" should be executed switching from one item with callback to one item without as previously.

Actual Behavior

Both items have no callback and the warning is tipped. However, this is an easier test than when switching between 2 items.

Other comments

When simply changing back first item to { text: 'Hello', callback: () => {} }, the test does not pass.

I put it in the wrong package. Moved issue to vuetifyjs/vuetify#6810
