HsImport inserts module between function and Haddock documentation.

[fendor]

Has been reported upstream hsimport/#16. We have to wait for a new release, then this issue can be closed.

Example is roughly taken from stack new test haskeleton
Example.hs

-- | An example module.
module Example (main) where

-- | An example function.
main :: IO ()
main = return ()

foo :: IO ()
foo = do
    _ <- async $ return ()
    return ()

> hsimport -m "Control.Concurrent.Async" Example.hs

Output:

-- | An example module.
module Example (main) where

-- | An example function.
import Control.Concurrent.Async
main :: IO ()
main = return ()

foo :: IO ()
foo = do
    _ <- async $ return ()
    return ()

Expected:

-- | An example module.
module Example (main) where

import Control.Concurrent.Async
-- | An example function.
main :: IO ()
main = return ()

foo :: IO ()
foo = do
    _ <- async $ return ()
    return ()

Happens when using the code action to import a module.
