phabricator: avoid passing None to pycompat.fsdecode

"""simple Phabricator integration (EXPERIMENTAL)
This extension provides a ``phabsend`` command which sends a stack of
changesets to Phabricator, and a ``phabread`` command which prints a stack of
revisions in a format suitable for :hg:`import`, and a ``phabupdate`` command
to update statuses in batch.
A "phabstatus" view for :hg:`show` is also provided; it displays status
information of Phabricator differentials associated with unfinished
changesets.
By default, Phabricator requires ``Test Plan`` which might prevent some
changeset from being sent. The requirement could be disabled by changing
``differential.require-test-plan-field`` config server side.
