fix(material/datepicker) debugging VoiceOver not reading date on Page…

…Down Do not merge this pls. Debugging issue angular#2430. There seems to be two issues 1. The screenreader focus doesn't not match the browser focus 2. the aria-live region is interfering with reading the focused element Adds a timeout to fix #1, and removes the aria-live region to fix angular#2. This is not the final solution, requires more investigation... Relates to angular#24330
