tests: Fix test compatibility with Python 3.14 forkserver

Python 3.14 changed the default multiprocessing start method on Linux
from "fork" to "forkserver". The test_forall_all_projects_called_once
test uses mock.patch.object on Project.GetRevisionId, but class-level
mock patches do not survive into forkserver worker processes because
they start from a clean Python interpreter rather than inheriting the
parent's memory.

Replace the mock with setting revisionId directly on each Project
instance so GetRevisionId() short-circuits without touching git.
This works with any multiprocessing start method since the string
attribute is part of the Project objects stored in _parallel_context,
which is properly serialized to workers via initargs.
