The cache_fullpath for the Stylesheet::Manager was the same for
every test runner in a parallel test environment, so when other
specs or other places e.g. the stylesheets_controller_spec ran
rm -rf Stylesheet::Manager.cache_fullpath this caused errors
for other specs running that went through the
Stylesheet::Manager::Builder#compile path, causing the error
```
Errno::ENOENT:
No such file or directory @ rb_sysopen
```
Also fixed the stylesheet_controller which was interpolating Rails.root + CACHE_PATH
itself instead of just using Stylesheet::Manager.cache_fullpath
