Removing a hack for CNG

However, two other "hacks" had to be added to maintain bit-exactness
with legacy.

Note that this change requires a new version of the universal.rtp test
input, although the output reference stays the same.

Moving reference files, and using a new input vector for NetEq4.
The new input vector neteq_universal_new.rtp is identical to the old
neteq_universal.rtp, except that the payload type for CNG packets that
follows a wideband codec is changed to 98.

Update to resources revision 15 where the new reference files are.

Also changing a faulty log error.
