Use response_time_percentile for <name>_stats.csv file instead of current_response_time_percentile

[mehta-ankit]

Using --csv flag in 0.13.3 version of locust (after #1146 was merged) only prints percentiles in the sliding window of CURRENT_RESPONSE_TIME_PERCENTILE_WINDOW. This happened because instead of using get_response_time_percentile() function i used get_current_response_time_percentile() in requests_csv() function.

@heyman @cyberw Made a small mistake in my previous PR (refactoring of CSV related code) that merged recently. Created an issue to track it:
#1198
