fix(select): remove workaround for Chrome bug

In the Chrome issue (https://bugs.chromium.org/p/chromium/issues/detail?id=381459)
I noticed that the bug can't be reproduced in Chrome 45 and the issue was
closed subsequently. I've also tested again with Chrome 51 and it still works.

Additionally, the Chrome hack was kept in the select code, but wasn't ported to
the ngOptions code when the two split in 7fda214c4f65a6a06b25cf5d5aff013a364e9cef,
and no regression happened.

Nevertheless, a test has been added to guard against a future regression.
