miq_tabs_init - use observe queue for tab switching too

[himdel]

Since many tab switches are in forms, especially non-angular form, we have a timing bug where a tab switch request can happen before all the changes to inputs are processed.

Changing so that tabs use the observe queue as well.

@himdel Is the miqJqueryRequest something we can detect by invoking some javascript? We have a hook that is called before the tab is clicked, so I was thinking we could call something and wait for it to be gone before going on the tab.

@mfalesni $.active, you're already doing that. The problem is you have to wait for the other requests before switching tabs, and some inputs only do the request on blur - after clicking somewhere else, like, a tab :).

Everything looks fine. 👍

@himdel Hmm, then it should be possible to do something like:

getCurrentlyFocusedElement().blur();

That would then let the requests kick off and we could grab it with our standard in-flight check, right?
