phabricator: avoid a stacktrace when command arguments are missing

Previously, the TypeError wasn't properly converted to a SignatureError when
improper arguments were supplied to the inner function, because the stack depth
is 2 inside the vcrcommand decorator.  The `__name__` and `__doc__` attributes
need to be reassigned to the new wrapper so that the help summary is available.
