qa: remove data provider test cases that fail without strict mode

Per a comment from @simPod, removes the following:

- From `RequestIntegrationTest::getInvalidMethod()`:
  - The test cases for 1 and 1.01 (integer and float)
- From `ResponseIntegrationTest::getInvalidStatusCodeArguments()`:
  - The test cases for 200.34

Additionally, this patch adds keys to each entry returned by these two providers, to better facilitate understanding which test failed.

The removals were necessary as the test case does not enable strict mode, and these particular types can be converted to the specified type "safely", leading to false negative results.
