storage/app/themes not auto-generated

[kaidesu]

Describe the issue

When installing the CMS from a fresh Laravel installation or running a fresh suite of tests, tests immediately fail as the storage/app/themes directory is not present or generated. This directory is responsible for storing the cached theme manifests.

To reproduce

1. Grab a fresh copy of the CMS package
2. composer install
3. phpunit

Expected behavior

The necessary directory to be created if it doesn't exist.

Version and browser

Version: v6.0.0 Beta 9
