inline-requires handles Identifiers declared before CallExpressions

[bvaughn]

While syncing the latest React release to fbsource I discovered an improperly handled inlining case.

Essentially this:

function foo() {
  bar();
}
var bar = require('baz');
foo();

Became this (and errored because bar was undefined):

function foo() {
  bar();
}
foo();

After this bugfix it becomes:

function foo() {
  require("baz")();
}
foo();
