Tracks build warnings

[JedMeister]

After this conf.d/main line:

bundle --without=test install

This warning shows in Tracks build log:

[DEPRECATED] The --without flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use bundle config set --local without 'test install', and stop using this flag

[JedMeister]

I note that 'testing' is no longer being explicitly being skipped in the install process of the current (v18.0) release. And the --without switch is not being used either. Instead the "withouts" are being added to the bundle config. I.e.:

bundle config set --local without 'postgresql sqlite'

I'll leave this issue open but have downgraded it to a "feature" as not installing the 'testing' target will only reduce the size of the appliance and shouldn't make any material difference to it's functionality. In fact there is a risk that it might actually break something (if there are some dependencies that have been incorrectly included in the 'testing' target)...
