Refactor REST API tests to use block-based patterns

- Remove SFNativeRestRequestListener and create SFRestAPITestResponse class
- Refactor tests to use XCTestExpectation instead of custom listeners
- Fix forceTimeoutRequest double callback bug in SFRestAPI.m
- Add SFRestAPITestDelegate helper for delegate-based API testing
