File assets not always placed next to style/script dist file

[Cory Hughart]

Asset file placement works fine for files in the root of /src/styles/ and /src/scripts/, but adding additional entry globs for nested paths (such as src/styles/blocks/*/*.* for block-specific CSS) in a project's config leads to asset files being placed in the relative /dist/css/ or /dist/js/ root dir while the style/script file is correctly placed at the relative nested output path.
