client.search responds with "ConnectionError" with a string "attributes" search option

[trentm]

Doing an ldapjs client search using the "attributes" search option erroneously set to a string (instead of an array) errors out with "ConnectionError"... i.e. the connection to the ufds server is lost. Would be nicer if that either threw immediately on the client.search with invalid input... or returned a more reasonable error and not bounce the connection.

 base = 'ou=users, o=smartdc'
 uuid = '11111111-1111-1111-1111-111111111111'
 searchOpts = {
   filter: '(&(uuid=' + uuid + ')(objectclass=sdcperson))',
   scope: "one",
   attributes: "dn"
 };
 client.search(base, searchOpts, function(err, result) {
   if (err) {
     console.log("search start error")
     return callback(err);
   }
