Invalid exports for Svelte

[ColinTimBarndt]

When using the plugin in the Svelte (Rollup) config, this is what the generated code file will look like with default settings:

export default undefined

And when using raw:

export default "export default \"/src/icons/rj45.svg\""

Without this plugin, the emitted module is export default "/path/to/image", which is the fallback for any file.
My suspicion is that the plugin resolves the SVG image in the same way and therefore receives no valid SVG as input. It would also be great if the plugin would print a warning in this case.
