Fix maniphest "create" transactions

Summary: the quotes are 'cuz "create" is inferred. Previously, we inferred on "status", but since we set that on "initializeNewTask" instead infer off "title" (aka "name") like most other apps do. Only hairy tweak was to elevate TYPE_TITLE to the most important of all maniphest transactions, which doesn't actually seem too unreasonable if not correct even? Fixes T4686.

Test Plan: made a new task, used bin/mail, got the right headers (mail vary prefix == created)
