extract_first_word: Refactor EXTRACT_DONT_COALESCE_SEPARATORS handling
Refactor allocation of the result string to the top, since it is currently done in both branches of the condition. Remove unreachable code checking for EXTRACT_DONT_COALESCE_SEPARATORS when state == SEPARATOR (the only place where SEPARATOR is assigned to state follows a check for EXTRACT_DONT_COALESCE_SEPARATORS that jumps to the end of the function.) Tested by running test-util successfully. Follow up to: 206644aedeb8859801051ac170ec562c6a113a79
