Merge branch 'ps/ref-transaction-hook'

The logic to find the ref transaction hook script attempted to
cache the path to the found hook without realizing that it needed
to keep a copied value, as the API it used returned a transitory
buffer space.  This has been corrected.

* ps/ref-transaction-hook:
  t1416: avoid hard-coded sha1 ids
  refs: fix interleaving hook calls with reference-transaction hook
