ASTs differ when type family result is declared using `=`

[alexpeits]

Ormolu can format this:

{-# LANGUAGE TypeFamilies #-}
type family TF a b :: result where
  TF a b = Int

but not this:

{-# LANGUAGE TypeFamilies #-}
type family TF a b = result where
  TF a b = Int

Both are accepted by ghc (e.g. loading them in ghci). The syntax doesn't make a difference but it's required for usage with TypeFamilyDependencies.

Command run: ormolu -d <filename>

Output:

warnings:

parse result:
  comment stream:

AST of input and AST of formatted code differ.
  at TF.hs:2:20-27
Please, consider reporting the bug.

This is now fixed.

That was quick, thanks!
