suggestion(test): default to building tests

[jtfairbank]

@veryeli suggested we have the default yarn test script include a build, and then have a yarn test:without-build script that runs the tests again without rebuilding. This seems like it'd help prevent build issues when changing from the dev server to running tests while still allowing us to skip building when running multiple tests in a row.

Does this mean we want to remove the test:with-build script?

Update:
After speaking with Taylor we are removing the test:with-build
