On first setting up a new namespace/production, config file doesn't get properly imported if .cls mapping differs from upstream

When setting up a new namespace for the first time with @isc-pbarton 's help, we encountered an issue where the plugin settings would not update from an upstream embedded-git-config.json , apparently because the default mapping for .cls files (/cls/) differed from that of the upstream config file (/src/). The expected behavior is that the plugin imports the new settings on a force import all from upstream.
