APP_PATH redefined

[paneer-tikka]

Since this gem (re)defines APP_PATH, we get the following warning when starting rails.
/usr/local/bundle/bundler/gems/standalone-migrations-51197b69f14d/lib/standalone_migrations.rb:13: warning: already initialized constant APP_PATH bin/rails:2: warning: previous definition of APP_PATH was here
We were ignoring this until we realised that it caused issues with other gems (in particular doorkeeper) which assumed a different APP_PATH while generating files.
We were able to work around it by commenting it out temporarily, but is there a better way to fix this? Any suggestions? Would be happy to raise a PR if we can.

I'm not sure about this, but isn't the standalone_migration gem made to be able to use active_record migrations and commands without rails?

EDIT: Yes it is: Rails migrations in non-Rails (and non Ruby) projects.
Is there a reason for you to use the gem in a Rails project, then? If not, it would be best for you to just remove the dependency to the standalone_migration gem and let Rails do everything :)
