fix: keep function target file when noBundle is set (#14)

## Why?

We should only delete the file when it was created by us. If the user
sets the --noBundle flag, we should not delete that file, as it wasn't
created by the CLI.

## How?

- Check if the noBundle flag is set before deleting the file.

## Tickets?

- no ticket

## Contribution checklist?

- [x] The commit messages are detailed
- [x] The `build` command runs locally
- [ ] Assets or static content are linked and stored in the project
- [x] You have manually tested
- [ ] You have provided tests

## Security checklist?

- [x] Sensitive data has been identified and is being protected properly
- [x] Injection has been prevented (parameterized queries, no eval or
system calls)
