fix(date): parse string input as local time unless TZ is specified

previously we were always parsing the string input as UTC which cased issues like:

{{ '2012-04-01' | date:'d MMM yyyy' }} renders as 31 Mar 2012

BREAKING CHANGE: string input without timezone info is now parsed as local time/date

Closes #847
