crash with --require

[martin-volf]

Command-line options like --require cause lux to crash:

#lux --require CONFIG_DIR test.lux 
summary log       : /base/lux_logs/run_2015_08_13_14_43_08/lux_summary.log


FATAL ERROR: /base/lux_logs/run_2015_08_13_14_43_08/lux_summary.log:

                                  [{file,"lux_suite.erl"},{line,424}]}]

After the commit 7e8e9a command line option arguments are no longer grouped, but merge_env_opt obviously expects that they are.

Thanks for the precise bug report! I am looking into this.
