false positive no-unused-modules with Flow

[Hypnosphi]

When type import goes before default import from the same file, the default export is marked as unused:

// foo.js

// @flow strict
export type Foo = string
export default ''

// index.js

// @flow strict
import type {Foo} from './foo'
import foo from './foo'

3:1 error exported declaration 'default' not used within other modules import/no-unused-modules

It works OK if I change the imports order:

// index.js

// @flow strict
import foo from './foo'
import type {Foo} from './foo'

The issue is rather importing from the same source 2 times than importing a flow type. I already have a workaround in place to fix the current behaviour, will make a PR after #1542 is merged.

Now that #1542 is merged, do you have any plans to publish your workaround, @rfermann?
