  Fix crash when calling script functions with omitted optional params

The crash would happen if the script function is exported with the
CMD_PARAM_FIX_NULL flag and does not actually change the parameter
value. Currently, only forward() uses the flag in this manner and
is the only function affected by this crash.

(cherry picked from commit 278c1646451ab75196e0440c15047d25a7b4b2f4)
