test: -- reaches neither the project args nor the script

Browse source 
`run -- record -- a` has to run the record script with the args `--`
and `a`: the first `--` ends the options, the second comes after the
script's name and is the script's. The project args keep only what
stood before `run`. And `run -- -x` has to look for a script called
-x, since after `--` an option-like word is an operand. Before the fix
the first `--` showed up in the project args, and `-x` joined it there
while the bare `run` listed the scripts and succeeded.
