Thanks to our build orchestration tooling, there is
no reason for us to build all of the packages on
`install`. In cases where `prepare` was used to
build before packaging, this changes it to
`prepack` so it will run only under the correct
circumstances.
This commit replaces the moxios package with the
axios-mock-adapter, in order to fix all of the failing
tests. This felt necessary because changing the
TypeScript configuration would have the largest
potential impact on this package, due to it
being written natively in it. This package is a
great candidate for testing all of the new
configuration changes out on.
