Bugfixes:

• Make FromJSON instance for Qualified backwards compatible (#4403 by @ptrfrncsmrph)

  Prior to #4293, Qualified was encoded to JSON such that

  >>> encode $ Qualified Nothing "foo"
  [null,"foo"]
  >>> encode $ Qualified (Just $ ModuleName "A") "bar"
  ["A","bar"]

  The type of Qualified has changed so that null no longer appears in JSON output, but for sake of backwards-compatibility with JSON that was produced prior to those changes (pre-v0.15.2), we need to accept null, which will be interpreted as Qualified ByNullSourcePos.

• Fix extraneous qualifiers added to references to floated expressions (#4401 by @rhendric)
