Widgets inheriting from TextBox cause IE error when destroyed immediately after instantiation

​https://github.com/dojo/dijit/blob/master/form/TextBox.js#L122

causes a nodeType is null or not an object when destroying the widget quickly. I noticed this behavior in a jasmine test in ie.

there shouldnt be functions that rely on objects that may not exist.

This affects everything that inherits from textbox - filteringselect etc.

A quick fix is adding if (this._beingDestroyed) { return; } to the setTimeout.

But should the setTimeout be refactored to some other means?

It's an edge case that started in 1.5 but easy to workaround by just expanding the try/catch that's already there.

Fixes #13805. Expand existing try/catch to encompass the getComputedStyle call.
