changectx: use unfiltered changelog to walk ancestors in annotate
Since we are only walking ancestors, it is safe to use an unfiltered repository.
(Because if the original rev is not filtered, none of its ancestors will be).
Differential Revision: https://phab.mercurial-scm.org/D7501

"eqeqeq" : true, // true: Require triple equals (===) for comparison

"nonbsp" : true, // true: Prohibit "non-breaking whitespace" characters.
"undef" : true, // true: Require all non-global variables to be declared (prevents global leaks)
