Fix sonar issues in Command line editor
THe Apex command line editor had issues in teh way its loops for processing commands were written. The loops are simplified in this review. Issue-ID: POLICY-1034 Change-Id: If684a57de79bd56211e1ca3e8c446bd9698666be Signed-off-by: liamfallon <liam.fallon@ericsson.com>
