Title: Index js css fix

Issue \#3993 was about Sprockets not acting as documented in production environments.

Specifically, during assets precompile, 'javascript_include_tag' is supposed to notice when the included path is a directory, and use an 'index.js' or 'index.css' file from inside that directory as a manifest:

http://guides.rubyonrails.org/asset_pipeline.html#using-index-files

\#3993 was closed when a fix (SHA: df8457748ebbfa092c4c10aedda57aeef2f28776) was merged. The problem is that the fix is not only incorrect, it actually introduced a new bug.

The fix as merged converts paths pointing to index.* files into paths pointing at their enclosing directories. This is the opposite of the documented behavior -- if the original path is a directory, 'index' needs to be *added* to the path to find the file inside the directory.

That commit therefore broke asset precompile such that any existing asset files named 'index.(js|css)' are completely skipped over, without fixing the original issue. This commit fixes the new bug and makes the feature work as documented, actually resolving \#3993.
