Only first lifecycle hook runs

**Describe the bug**
When `beforeDone` lifecycle hook is a list, only the first hook runs

**To Reproduce**
Steps to reproduce the behavior:

1. My GraphQL schema:

```graphql
# Put your schema here
```

2. My GraphQL operations:

```graphql
# Put your operations here
```

3. My `codegen.yml` config file:

```yml
overwrite: true
schema:
- './packages/schema/schema/*.graphql'
documents:
# Shared fragments, used both by frontend and by backend tests
- ./packages/schema/fragments/*.gql
generates:
# Common types shared by backend, web frontend and mobile are generated in schema package
# Common validation schemas are also in schema package
./packages/schema/src/__generated__/types.ts:
# ...

config:
preResolveTypes: true

hooks:
afterAllFileWrite:
- prettier --write
beforeDone:
- touch a.txt
- touch b.txt

```

**Expected behavior**

I expect both files `a.txt` and `b.txt` to be created. However, only `a.txt` is created
