test: invoke yarn backend only once (#784)
Summary:
Lots of tests need the output of `yarn backend`. Before this commit,
they tended to create it themselves. This was slow and wasteful, and
also could in principle have race conditions (though in practice usually
tended not to).

This commit updates tests to respect a `SOURCECRED_BIN` environment
variable indicating the path to an existing directory of backend
applications.

Closes #765.

Test Plan:
Running `yarn test --full` passes.

Prepending `echo run >>/tmp/log &&` to the `backend` script in
`package.json` and running `yarn test --full` results in a log file
containing only one line, indicating that the script really is run only
once.
