Mac app won't launch due to multiple 'couch*' items

Farshid reported the Mac 'Couchbase Server' app wouldn't start on his machine, though it starts on mine. Turns out his build contains three items matching 'couch*' in couchbase-core/lib/couchdb/erlang/lib, and the line in start-couchbase.sh that finds the right couchdb binary doesn't work correctly if there are multiple matches.

I changed the pattern to 'couch-*' for which there is only one match. That fixes it, says Farshid.
