context: remove unreliable accessor methods from committablectx

There are two caching routes for (propertycache-ed) "_status" below in
committablectx:

  - invoking "status()":

    "dirstate.status()" is invoked, and the result of it is cached
    into "_status". In this case, any of "listignored", "listclean"
    and "listunknown" may be True.

  - accessing "_status" directly before "status()":

    Own "status()" is invoked, but all of "listignored", "listclean"
    and "listunknown" arguments are False, in this case.

"ignored"/"clean"/"unknown" accessor methods of "committablectx" use
corresponded fields of "_status", but these fields aren't reliable,
because these fields are empty when:

  - "_status" method is executed before accessors, or
  - "status()" is executed with "list*=False" before accessors

In addition to it, these accessors aren't used in the recent Mercurial
implementation. At least, removing them doesn't cause any test
failures.
