Add tests for chained reexports from a hybrid module

[lettertwo]

This adds two tests that fail prior to #7944

 
  1) scope hoisting
       es6
         should support chained reexports from hybrid modules:
     a.js:56
output = (/*@__PURE__*/$parcel$interopDefault($d2UUm)) + $8693f62e1d3f1804$exports.bar;
                                                         ^

ReferenceError: $8693f62e1d3f1804$exports is not defined

  2) scope hoisting
       es6
         should support chained reexports as default from hybrid modules:
