Missing parentheses at FunctionExpression inside CallExpression inside SequenceExpression

[leumasme]

The following Code will generate a Function Expression inside of a Call Expression inside of a Sequence Expression.
(function(){})(), stuff()
When parsed and prettyPrinted through recast, it will print out the following, syntax-invalid, code:
function() {}(), stuff();

Yep, reproduced this as follows:

const recast = require('recast')
const ast = recast.parse('(function(){})(), stuff()')
recast.parse(recast.prettyPrint(ast).code) // throws 'Unexpected token ('

This issue no longer reproduces 🎉.

It was fixed by #1057: the issue still reproduces at the commit before that, and no longer does at that commit.
