able to set --recovery-type=delta for node that has been failovered with --force

http://qa.sc.couchbase.com/job/centos_x64--00_02-graceful-failover-cli/1/consoleFull

./testrunner -i /tmp/gracefulfailover-cli.ini get-logs=True,get-delays=true,GROUP=GRACEFUL,upr=True -t clitest.couchbase_clitest.CouchbaseCliTest.testAddRemoveNodesWithRecovery,nodes_add=1,nodes_rem=0,nodes_failover=1,nodes_readd=1,nodes_recovery=0,GROUP=GRACEFUL

steps:
1)2 nodes in cluster
2) force failover 1 node
3) end then try to set --recovery-type=delta for failovered node

Expectations:

cli_command = "recovery"
for num in xrange(nodes_failover):
#negative case will try recovery when nodes failovered
options = "--server-recovery=

{0}:8091 --recovery-type=delta".format(self.servers[nodes_add - nodes_rem - num].ip)
output, error = remote_client.execute_couchbase_cli(cli_command=cli_command, options=options, cluster_host="localhost", user="Administrator", password="password")
self.assertEqual("ERROR: unable to setRecoveryType for node ns_1@{0}

(400) Bad Request".format(self.servers[nodes_add - nodes_rem - num].ip), output[0])
self.assertEqual("

{u'otpNode': u\"invalid node name or node can't be used for delta recovery\"}

", output[1])

I saw it on earlier version, seems to me it is a regression
