Update residential and commercial building recovery output file names

[navarroc]

When residential and commercial building recovery analyses run, both of them create two recovery outputs, one ends with "_recovery.csv" and the other ends with "time_stepping_recovery.csv". These need to be differentiated because when the tool is ran as a workflow, there is no way to determine which file should be stored with which output in a generic name. Looking for files *_recovery.csv" will return both files. Since the output description for the first is "CSV file of residential building recovery time", maybe we can name the output as result_name + "_recovery_time.csv" instead of result_name + "_recovery.csv".
