BUG/MINOR: lua: lua-load doesn't check its parameters

Browse Source 
"lua-load" doesn't check if the expected parameter is present. It tries to
open() directly the argument at second position. So if the filename is
omitted, it tries to load an empty filename.

This patch could be backported until 1.8
