"default" isn't included in groups on transitive dependencies listed explicitly in other groups

[alyssais]

Suppose I have a Gemfile like this:

source "https://rubygems.org"
gem "actioncable"
gem "websocket-driver", group: :test

The gemset.nix generated by Bundix 2.4.1 will set ActionCable's groups to [ "default" ], and websocket-driver's to [ "test" ]. This means that the generated bundlerEnv wouldn't include websocket-driver unless the test group was included, even though it's required by the default group.
