speedtest-csv --help incorrectly claims speedtest-cli needs to be installed

[Henrik Bengtsson]

Example:

$ speedtest-csv --help
speedtest-csv 2.0.0
[...]
Installed dependencies:
 speedtest-cli <PLEASE INSTALL> (https://github.com/sivel/speedtest-cli)
 python 2.7.12

This is with:

$ which speedtest-cli
/usr/bin/speedtest-cli
$ which speedtest-csv
/home/hb/bin/speedtest-csv

Not a critical problem, but misleading.
