Automatically populating $HTTP_RAW_POST_DATA is deprecated

Hi,

I have the following error when I run tests of this extension.

      │ --- Failed steps:
      │ 
      │     And the response should contain json: # features/send_raw.feature:16

The extension does not rely on the deprecation feature. you can turn it off in your php.ini (there is no way to avoid the deprecation warning if the feature is turned on, even though you never read $HTTP_RAW_POST_DATA, as the warning is triggered very early in the request processing)

and we cannot change the ini setting ourselves either, as it would be too late (the processing of the input request happens before calling the userland code)

OK thanks.
In fact it works fine on my production server but not on the travis-ci platform.
I will investigate according to your comments.
