revert(select): avoid checking option element selected properties in render

This reverts commit dc149de9364c66b988f169f67cad39577ba43434. That commit fixes a bug caused by
Firefox updating `select.value` on hover. However, it
causes other bugs with select including the issue described in #7715. This issue details how
selects with a blank disabled option skip to the second option. We filed a bug
with Firefox for the problematic behavior the reverted commit addresses
https://bugzilla.mozilla.org/show_bug.cgi?id=1039047, and alternate Angular fixes are being
investigated.

Closes #7715 #7855
