can't drop continuous query

[neonstalwart]

this is with 0.9.0-rc22

# create a db
curl -G http://127.0.0.1:8086/query --data-urlencode "q=create database mydb"
{"results":[{}]}

# create a continuous query
curl -G http://127.0.0.1:8086/query --data-urlencode "db=mydb" --data-urlencode "q=create continuous query test on mydb BEGIN select count(*) as count into \"10m.test\" from test group by time(10m) END"
{"results":[{}]}

# show the continuous queries
curl -G http://127.0.0.1:8086/query --data-urlencode "db=mydb" --data-urlencode "q=show continuous queries"
{"results":[{"series":[{"name":"mydb","columns":["name","query"],"values":[["test","CREATE CONTINUOUS QUERY test ON mydb BEGIN SELECT count(*) AS count INTO \"mydb\".\"default\".\"10m.test\" FROM \"mydb\".\"default\".test GROUP BY time(10m) END"]]}]}]}

# drop the continuous query - this result doesn't look right
curl -G http://127.0.0.1:8086/query --data-urlencode "db=mydb" --data-urlencode "q=drop continuous query test on mydb"
{}

# show the continuous queries - should be empty
curl -G http://127.0.0.1:8086/query --data-urlencode "db=mydb" --data-urlencode "q=show continuous queries"
{"results":[{"series":[{"name":"mydb","columns":["name","query"],"values":[["test","CREATE CONTINUOUS QUERY test ON mydb BEGIN SELECT count(*) AS count INTO \"mydb\".\"default\".\"10m.test\" FROM \"mydb\".\"default\".test GROUP BY time(10m) END"]]}]}]}
