nearley-unparse produces strings that throw errors with nearley-test

[correcthorsebatterystaple]

When running nearley-unparse grammar.js the output is a string of brackets, however, this is not a valid string in my grammar and nearley-test grammar.js --input <bracket-string> confirms this by throwing an error.

Grammar: https://pastebin.com/BW5fFChR

Expected: nearley-unparse returns a valid string of the grammar Actual: Returns a string of brackets which is invalid in the grammar

Example run:

> npx nearley-unparse .\src\grammar.js -n 1 -d 15
()()()()()()()

> npx nearley-test .\src\grammar.js --input "()()()()()()()"
