dirs._addpath: reinstate use of Py_CLEAR

I changed this to an explicit Py_DECREF + set to null in 6f0e6fa9fdd7. This was
a silly misunderstanding on my part -- for some reason I thought Py_CLEAR set
its argument to null only if its refcount reached 0. Turns out that's not
actually the case -- Py_CLEAR is just Py_DECREF + set to null with some
additional precautions around destructors that aren't relevant here.

The real bug that 6f0e6fa9fdd7 fixed was the fact that we were mutating the
string after setting it in the Python dictionary.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
