Improvements to v8::Persistent usage (issue #1001):

- Remove V8_USE_UNSAFE_HANDLES dependency.
- Don't create persistent handles for primitive types.
- Don't create persistent handles for stack traces.
- CefV8Value::IsObject() no longer returns true for Date types.
- Fix V8Test.ContextEntered test flakiness.
