Preserve the order of the elements that are not part of a case nor default in
a ng-switch directive
BREAKING CHANGE: elements not in the ng-switch were rendered after the
ng-switch elements. Now they are rendered in-place.
Ng-switch directives should be updated with non ng-switch elements
in render-order. e.g.
The following was previously rendered with <li>1</li> after "2":
<ul ng-switch="select">
<li>1</li>
<li ng-switch-when="option">2</li>
</ul>
To keep the old behaviour, say:
<ul ng-switch="select">
<li ng-switch-when="1">2</li>
<li>1</li>
</ul>
Closes#1074
The leak can occur when ngSwich is used inside ngRepeat or any other
directive which is destroyed while its transcluded content (which
includes ngSwitch) is not attached to the DOM.
Refactor ngSwitch to use controller instead of storing data on compile
node. This means that we don't need to clean up the jq data cache.
Controller reference is released when the linking fn is released.
Closes#1621
