echo reference: fix buffer overflow

commit 33e8f78b introduced a regression causing the input buffer
size to be underestimated when downsampling and doing stereo to mono
conversion.

Also a test in create_echo_reference() was not removed and prevented
write sampling rates lower than read sampling rates.
