MOD-14486: Fix crash on odd word count in space-separated moduleArgs

fix_modulesArgs crashed with sys.exit(1) when a space-separated
moduleArgs string had an odd number of words. This is a valid scenario
when module args have single-word flags or multi-word values.

Instead of crashing, fall back to treating the string as a single arg
(the pre-v0.7.22 behavior) when the word count is odd.
