If the Khepri application is started and any of the default applications (mnesia, sasl, ssl, and khepri itself) are not available,
application:get_key/2
will returnundefined
, causing a badmatch that will terminate the Khepri application. Instead we can gracefully handle these applications being unavailable and not include their modules in the list of modules to skip when extracting functions.Fixes #214
