    ZEPPELIN-2833 JDBC Interpreter doesn't follow JDBC specification when…

    … getting the results.
    
    ### What is this PR for?
    
    Fix for ZEPPELIN-2833. JDBC Interpreter uses result set next() method after 
it's already reached the end. According the JDBC documentation that may cause 
SQL exception.
    
    ### What type of PR is it?
    Bug Fix
    
    ### Todos
    None
    
    ### What is the Jira issue?
    
    https://issues.apache.org/jira/browse/ZEPPELIN-2833
    
    ### How should this be tested?
    
    Use Phoenix 4.7+ select * query for tables that have less than 1000 
records. Without patch an exception about closed Result set will be thrown.
    
    ### Questions:
    * Does the licenses files need update?
    No
    * Is there breaking changes for older versions?
    No
    * Does this needs documentation?
    No
