fix(select): fix blur event not triggering, focus styles in containers

[rschmukler]

DO NOT MERGE ME YET

This issue was the culprit for the select double label when invalid error that was discussed by @jelbourn and @topherfangio in slack.

I have no idea why this fix works. Specifically, focus fires but blur does not with the jqlite on methods. I'd love to hear from anyone who has ideas on why this might be (ping @jelbourn, @ThomasBurleson, @robertmesserle)

I changed the focus listener for consistency, but this feels weird and I'd much rather get to the bottom of the issue than this quick-fix.

It is obviously because of https://github.com/angular/material/blob/select-blur-fix/src/components/select/select.js#L192-L194.

@gkalpak haha, yes obvious indeed. Sometimes a 2nd set of eyes is all it takes :P. Thanks

I think that's duplicating #6207
