Simplify CC handling in Maniphest

Summary: This fixes a bug where doing an "Add CC" on a task you were not CC'd on
would remove all the CCs except yourself. It also simplifies the CC handling
code a lot.
Test Plan:
  - Added myself and another user to a task neither of us were CC'd on (old
behavior: added both then removed them; new behavior: added both)
  - Added a user to CC with @mentions.
  - Made a comment on a task I wasn't CC'd on (I was CC'd).
  - Closed a task I wasn't assigned or CC'd on (I was not CC'd, but was
assigned).
  - Made an "Add CC" with new CCs and comment text (ccs added, text appeared).
  - Made an "Add CC" with no CCs and comment text (text appeared, transaction
correctly downgraded to "comment").
  - Made an "Add CC" with exsiting CCs and comment text (text appeared,
transaction correctly downgraded to "comment").
