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.
* Removed Changlogger Autoload
* Changed Jetpack Changelogger Formatter Loading
Rather than using the Composer autoload, we should use the
changelogger's "filename" option to point directly at the file.
This keeps the file out of the autoloads, since it's possible that
plugins or packages may be symlinked and break the relative
path to the plugin.
