NullPointerException is thrown unless isRunning() is called first

[bane73]

Forgive me if I have missed some config detail that this would resolve, I also did scan through current issues and am not finding anything about this (which is curious to me).

v0.3.7

public static void main(String[] args) {
  
    JenkinsServer jks = new JenkinsServer("https://jenkins.mydomain.com", "username", "token");
    
    // SAD PATH
    try {
             jks.getVersion(); 
    } catch(Exception e) {
             /* java.lang.NullPointerException
	      * at com.offbytwo.jenkins.JenkinsServer.getVersion(JenkinsServer.java:104)
              */
    }

    // HAPPY PATH
    jks.isRunning();
    jks.getVersion();
    
}

Yeah unfortunately you are right...The point is to get the version there must be at least a single communication happen with the Jenkins server otherwise this information is not set...so this needs to be fixed...Simplest solution would be to call isRunning() inside getVersion()...
