Sort performance report by URI. Fixes #23158

Fixes #23158

This is a simple fix that lists the performance reports table ordered by URI in alphabetical order. Implementation is similar to what was suggested in issue 23158.

Unit test is also included to test the ordered list, which required a new results file, JMeterResultsRandomUri.jtl. This files data is similar to what is in JMeterResults.jtl but with changes to the lb field as needed for the test.
