tempdir generator ordering issue

[calebhearth]

Steps to reproduce

(Guidelines for creating a bug report are available
here)

rails new rails52

Expected behavior

Tell us what should happen

The active storage generator is being run before the generator making tmp dirs, meaning the generator making the tmp dir itself is not needed.

Actual behavior

Tell us what happens instead

# clipped
      create  storage
      create  tmp/storage
       exist  tmp # <--- This should be moved before tmp/storage, or not run.
      create  tmp/cache
      create  tmp/cache/assets
#clipped

System configuration

Rails version: 5.2.0-beta2

Ruby version: ruby 2.4.2
