Add notary binary requirement for tests

This PR adds the "notary" binary requirement for tests.

Previously, NotaryHosting was checking for the "notary-server"
binary under the name notaryBinary. This renames that reference to
notaryServerBinary, so that notaryBinary can rightly refer
to the actual "notary" binary.

Currently only one test actually uses the notary binary, so it's been
updated accordingly.
