duplicated solidus_auth_devise in Gemfile

[gus-dovetail]

In my team, we have started a new ruby/spree project and then added the solidus gem, on top that I dockerised the whole application with all the moving parts we need.

What i've noticed is that whenever someone runs the command:

rails generate solidus:install \
            --migrate=true \
            --sample=true \
            --seed=true \
            --with-authentication=true \
            --payment-method=none \
            --auto-accept=true \
            --admin-email=admin@example.com \
            --admin-password=test123

Solidus adds the gem 'solidus_auth_devise' to the Gemfile without checking if it's already been added.

Solidus Version:

• solidus_core (3.1.5)
• solidus_auth_devise (2.5.4)
• solidus_api (3.1.5)
• solidus_backend (3.1.5)
• solidus_sample (3.1.5)
• solidus_social (1.4.0)
• solidus_support (0.8.1)

Context:

• Docker-compose.yml
• Dockerfile
• Entrypoint (here is where I run solidus:install)

That seems a bug, yeah. Would you like to attempt a PR to fix that @gus-dovetail? 🙂
