potassium install mailer does not update compose and .env.development files

[rjherrera]

While the recipe works correctly on creation, something weird happens when installing it afterwards. The mailer recipe relies on the background processor one, and while it should install everything necessary for the sidekiq config (compose, procfile, env vars, config, etc.) it does it partially.

I tried this in v6.2.0 and the compose file and .env.development were untouched.
