KSQL does not accept more queries when running QueryLimit - 1 queries

[spena]

Describe the bug
If the query limit is set to 20, then KSQL only allows executing 19 queries.

To Reproduce
Set the limit to 1 in the ksql-server.properties file:

ksql.query.persistent.active.limit=1

Open the CLI and execute one persistent query (it will fail):

ksql> create stream t1(id int) with (kafka_topic='t1', value_format='json', replicas=1, partitions=1);
 Message        
----------------
 Stream created 
----------------
ksql> create stream s1 as select * from t1;
Not executing statement(s) 'create stream s1 as select * from t1;' as it would cause the number of active, persistent queries to exceed the configured limit. Use the TERMINATE command to terminate existing queries, or increase the 'ksql.query.persistent.active.limit' setting via the 'ksql-server.properties' file. Current persistent query count: 1. Configured limit: 1.

Expected behavior
I should be able to execute as many queries as the limit allowed me (1 query in the above example).
