Fix sandbox generation

[luca-landa]

After creating a sandbox, the store is not mounted in config.rb and the migrations aren't copied and executed entirely.

There's this error in the process: Could not find generator 'spree:install'.

Currently, the Solidus sandbox generation is working, so it may be a problem with a specific dependency of this gem.

I'm doing some investigations here.

• I tried to move back to a commit of 1 month ago to check if we have a regression, but the problem looks the same - so It could be related to something wrong with an external dependency;
• after cloning the repo and running bin/rails-sandbox at some point I see a Could not find generator 'spree:install'.:

Dropped database 'db/development.sqlite3'
Database 'db/test.sqlite3' does not exist
Created database 'db/development.sqlite3'
Created database 'db/test.sqlite3'
Could not find generator 'spree:install'.
Run `bin/rails generate --help` for more options.
      create  config/initializers/devise.rb
         run  bundle exec rake railties:install:migrations FROM=solidus_auth from "."

It looks like that the issue is related to the change from spree:install to solidus:install (solidusio/solidus#3538) - but I'm still tracking down better what happened here.

Updating the spree:install line in bin/sandbox seems to solve the problem.

solidus:install should be available with the next release of solidus_dev_support.
When this happens we will need to run solidus extension . to apply the change to our bin/sandbox
