Fix test for TypedArrays.from on callable function

TypedArrays constructors are still callable even if they trigger a
TypeError Exception when a new target is not defined

Per https://github.com/tc39/test262/pull/484#discussion_r53228232

Remove unused harness file

Avoid Race Conditions in Test Runner

Promise: Add tests to disallow faulty optimization

Promise: Add test for constructor access count

Reorganize tests for Annex B extensions

Add tests for [[SetPrototypeOf]] on immutable prototype exotic objects

Add tests for _TypedArray_ constructors

The harness file `Test262Error.js` has not contained executable code since it
was introduced in this project [1]. The definition of the `Test262Error`
function has consistently been located in the `sta.js` harness file which test
runners are expected to inject into the test environment.

Remove the file and all references to it.

Object.prototype is extensible and an immutable prototype exotic object,
it's [[Prototype]] value is null
