New API breaks @import with load paths

[xzyfer]

@mgreter I started getting the following error

/Users/michael/Projects/Sass/test/css/swiftly/_settings.scss:6: file to import not found or unreadable: asimov-core/core
Current dir: /Users/michael/Projects/Sass/test/css/swiftly/

The first 7 lines of css/swiftly/_settings.scss are

$asimov-image-path: "/tasks/assets/img/";
$asimov-font-path: "/tasks/assets/";
$asimov-icon-path: "/tasks/assets/";

// Asimov.
@import "asimov-core/core";
@import "asimov-core/settings";

The command I'm running is

time /Users/michael/Projects/Sass/libsass/sassc/bin/sassc css/swiftly/_settings.scss -I components -I css settings.css

The asimov-core/core file exists in the components direct given in the load path

$  ls -l components/asimov-core/core.scss
-rw-r--r--  1 michael  staff  15182 21 Oct 14:20 components/asimov-core/core.scss

I did some digging and found the issue was introduced in 52f6857.

I hope is enough information.
