[FEATURE] Add Composer scripts to run unit tests (#503)

The `ci` script now also runs `ci:dynamic` which in turn runs `ci:tests`.

The PHPUnit cache is only applicable if the configuration is to run previously
failing tests first, which it isn't, hence `--do-not-cache-result`.

Also update the readme instructions for running all code checks.

Relates to #486.
