Remove remoteMap specific code left behind after the removal of the
remoteMap plugin in 6415784. The plugin interface should be versatile
enough to allow all of this code to reside inside the plugin itself.
Fix the incorrect error validation, be more lenient about empty values
and convert the checks to use async functions instead of error prone
callbacks.
Remove excessive getFactorioLocale checks in master.spec.
Ensure exceptions are properly passed down to the unit test framework
with promises, check the return status of requests, use config to
generate an access token, reduce code duplication and reformat to be
consistent.
