Incorrect formatting in fluent API call

[magnushiie]

TypeScript Version: 2.2.1

Code

Format the following code snippet using VS Code or typescript-formatter:

someVar
  .chain(
    'arg1',
    'arg2',
  )
  .chain(
    3,
    4,
  );

Expected behavior:

someVar
  .chain(
    'arg1',
    'arg2',
  )
  .chain(
    3,
    4,
  );

Actual behavior:

someVar
  .chain(
  'arg1',
  'arg2',
)
  .chain(
  3,
  4,
);

This is a common occurrence with fluent APIs (test frameworks, ORMs, etc) and tslint rules requiring trailing comma.

Note also that even without the trailing comma, the formatting is not correct:

someVar
  .chain(
  'arg1',
  'arg2'
  )
  .chain(
  3,
  4
  );

Duplicate of #5830

Indeed it's a duplicate of #5830, although the trailing comma here causes different formatting currently, so the fix should work with both with and without trailing comma - I will make a note on the other issue about this.
