redundant imports cause default-export version to not be transformed

[gregorjan]

When using named import from styled-components both babel and swc plugins are not used.

Funnily enough in codesandbox the behavior is exact opposite

Actually looking at your sandbox, it looks like only the button using the named import worked... I wonder if the plugin can handle one or the other but not both.
