Breadcrumbs incorrectly indents file icons when folder icons are disabled

[ghost]

When an icon theme does not specify any folder icons, breadcrumbs indents files which do have icons to the same level it would when there are folder icons. This behavior is confusing as it suggests that files can be children of folders in the same directory.

Steps to reproduce:

1. Install the insiders edition
2. Disable folder icons and open breadcrumbs -- No issues
3. Enable "minimal" icons and open breadcrumbs -- No issues
4. Enable "seti" icons and open breadcrumbs -- Alignment issue

Expected behavior:

When there are no folder icons, breadcrumbs should align file icons to the arrow sign; it should look similar to the explorer view.
