typing: disable a bogus attribute-error warning in phabricator

In a local pytype run, this fixes:

    File "/mnt/c/Users/Matt/hg/hgext/phabricator.py", line 359, in <lambda>:
        No attribute 'items' on bytes [attribute-error]
      In Union[Any, bytes]
    Called from (traceback):
      line 363, in process

The `bytes` case takes the previous `if` branch though.

# Filters traceback lines from stdin.
