md-3-line should align icons to the top IF ng-click is added

[asans]

The fix for #2589 does not fully fix the issue of top-aligning icons. The current fix only addresses the issue when the md-list-item is not clickable.

If and when one adds ng-click or ng-href to create a clickable list item, the style is no longer applied.

This is due to the following code:

a2b88be#diff-c3e997633bc56157521f1305098d447aL199

The selector:

   > md-icon:first-child {

Which only selects the immediate child of md-list-item. When ng-click is applied to md-list-item, there's an intermediate button injected into the system, causing the new style not to be selected.

Is there any chance you could provide a demo using the latest code so we can see if this is still an issue?

We really need a demo to investigate this further. Please provide a Codepen and we will reopen.
