fix(compiler): Push to stream in closures [LNG-365]

[DieMyst]

Description

This didn't work:

func addToStreamClosure(str: *string) -> string -> ():
  cl = func (s: string):
    str <<- s
  <- cl

func addToStream() -> []string:
  stream: *string
  cl = addToStreamClosure(stream)
  cl("one")
  <- stream

because str hasn't been renamed in inliner.

Proposed Changes

rename exports of closure body on renameExports
