phabricator: correct the default value of `phabhunk.corpus`...

phabricator: correct the default value of `phabhunk.corpus` There's only one caller to this constructor (which does provide this argument), and no direct assignments, so there's no runtime bug here. However, when pytype is tricked into using the standard `attr` package instead of the vendored version, it flags this because bytes is passed to the one constructor invocation. Tricking pytype into using the standard package will generate many more type hints, noteably around `@attr.s` decorated things.
