Bug description:ob_get_clean does not call the ob_start callback

Description:
------------
If you use ob_start with callback, the callback does not run, if you use
ob_get_clean() on the same output buffer. The callback get skipped,
which gives unexpected results. I think it is a bug.

Test script:
---------------
Expected output:
Parsed: asd<hr>


#1:
ob_get_clean:
http://sandbox.onlinephpfunctions.com/code/9444bc54b4311c456f7e0f26d936c55b7114417a
Output:
asd

#2 ob_get_contents + ob_clean
http://sandbox.onlinephpfunctions.com/code/f4aa458142dfdb7867d662983504689bbba191b8
Output:
Parsed: asd<hr>

Expected result:
----------------
Output:
Parsed: asd<hr>
