watchman: refactor transport connecting to unconfuse pytype

Pytype sees `self.proc` as potentially `None` here, even though it's set by the
`_connect()` logic.  Instead of asserting, simply use the process returned by
that method (which it sets into `self.proc` before returning, so there's no
functional change here).

#!/bin/bash

set -e
set -u

# Find the python3 setup that would run pytype
PYTYPE=`which pytype`
PYTHON3=`head -n1 ${PYTYPE} | sed -s 's/#!//'`

# Existing stubs that pytype processes live here
TYPESHED=$(${PYTHON3} -c "import pytype; print(pytype.__path__[0])")/typeshed/stubs
HG_STUBS=${TYPESHED}/mercurial
