extract_first_word: Refactor allocation in empty argument case

This covers the case where an argument is an empty string, such as ''.

Instead of allocating the empty string in the individual conditions when
state == VALUE, just always allocate it at the end of state == START, at
which point we know we will have an argument.

Tested that test-util keeps passing after the refactor.
