qa: updates psr-7 integration test version

Updates to 1.2.0, which adds the tests we wrote for mitigating ZF2015-05, with a few changes:

- When creating the string representation of the URL, we DO NOT normalize the path to remove multiple leading slashes.
  In its absolute form, this is not necessary.
- All normalization is done via `getPath()`; this mitigates the common XSS scenario.
- It adds a test to validate that when using origin-form during a `RequestInterface::getRequestTarget()` call, it will use the results of `getPath()`, as this is a scenario where the XSS could also occur.

I have removed one test from `UriTest`, as it contradicts the first point above.
Since the scenario is covered in the PSR-7 integration tests, we are covered.

See php-http/psr7-integration-tests#54 for more details.
