echo Test hook
Resolve a long-standing TODO item in bugreport.c of there being no centralized listing of hooks, this fixes a bug with the bugreport listing only knowing about 1/4 of the p4 hooks. It didn't know about the "reference-transaction" hook either. We can now make sure this is kept up-to-date, as the hook.c library will die if asked to find a hook we don't know about yet. The only (undocumented) exception is the artificial "test-hook" used in our own test suite. Move some of the tests away from the "does-not-exist" pseudo-hook, and test for the new behavior.
