CLONE - Don't export fuzziness or prefix_length when values less than 1

Currently Couchbase 6.5 does not accept a fuzziness value of 0 while Couchbase 6.0 did. As it stands the 2.7 SDK cannot make a search for an exact value in FTS.
This stops the code from outputting "fuzziness":0 or "prefix_length":0 allowing the search to succeed.
