Disposing of detached tooltips inside of a modal causes errors when you close a modal

[ambischof]

Found an Interesting bug:

Operating system: MacOS
Browser: Chrome 70.0.3538.77

JSFiddle: https://jsfiddle.net/anneb574/aq9Laaew/261755/
(or jsbin but it doesn't show what the error was)

If inside a modal, you create initialize a tooltipped element and then you detach that element and dispose of the tooltip, when you close the modal, it will cause an error:

tooltip.js:416 Uncaught TypeError: Cannot read property 'template' of null
    at Tooltip.getTipElement (tooltip.js:416)
    at Tooltip.hide (tooltip.js:349)
    at HTMLDivElement.<anonymous> (tooltip.js:493)
    at HTMLDivElement.dispatch (jquery-3.3.1.min.js:2)
    at HTMLDivElement.y.handle (jquery-3.3.1.min.js:2)
    at Object.trigger (jquery-3.3.1.min.js:2)
    at HTMLDivElement.<anonymous> (jquery-3.3.1.min.js:2)
    at Function.each (jquery-3.3.1.min.js:2)
    at w.fn.init.each (jquery-3.3.1.min.js:2)
    at w.fn.init.trigger (jquery-3.3.1.min.js:2)

I acknowledge that this is not the typical workflow (that is to detach the element before disposing of the tooltip) but when you're working with view frameworks, it sometimes happens.

I made a fix here: #27578 and created a JSFiddle with my fix see: https://jsfiddle.net/ojn3yuve/
