Reuse stream of HTTP request instead of create new stream

[ElGigi]

Reuse stream of HTTP request instead of create new stream.

If you can test with your test environment ;).

It does not seem to work properly when reusing the guzzle stream

Changed:

$this->assertEquals(stream_get_contents($stream, null, 0), $this->gitlabAdapter->read('README.md'));

To:

$this->assertEquals(stream_get_contents($stream), $this->gitlabAdapter->read('README.md'));

There was 1 failure:

Yes, my bad! JSON result... so not possible to reuse stream.

[ElGigi]

I read the API documentation; I hadn't seen the "../raw" route; so it works!

[RoyVoetman]

Nice! I should have known this, I even implemented a readRaw method in the client. Thanks for putting in the effort, I will add this in the new version when I have the time to test it in the testing environment.
