Fix the decompression in SR instrumented tests for API 21

[mariusc83]

What does this PR do?

In our SR instrumented tests we need to decompress the segments intercepted through the MockServer in order to be able to assess them with the expected payloads.
The segments are previously compressed with a deflate alg and we are using an Inflater instance in the SR tests to deflate them.
The Inflater class logic is buggy in the Android API 21 JVM. For some reason the inflater.finished method always returns false having our decompression logic running in an endless loop.
