Incorrect transformation of chained methods without indent

[ghost]

(repl)

decaffeinate is producing the wrong JavaScript based on my CoffeeScript input:

a
.b =>
  c
    .d
.e ->
  f

I get this output:

a
.b(() => {
  return c
    .d;
}).e(function() {},
  f
);

Here's what I expect it to be instead:

a
  .b(() => {
    return c
      .d;
}).e(() => f);

This is due to the .map and .sort chained methods not being indented in from data. Though poor syntax, this does produce valid javascript when ran through a coffeescript compiler: https://jdoodle.com/a/18FG

Looks like the bug is in MainStage since the output of NormalizeStage looks okay.

Updated the issue with the reduced version.
