Starting a bot with missing configuration may exit with code 1 instead of expected 78

### What Red version are you using?

3.5.20 and earlier

### What were you trying to do?

Attempting to launch the bot using the flag `--no-prompt`, with no token and/or prefix set up beforehand.

### What did you expect to happen?

Process to exit with code 78 for configuration error as expected in the following lines:
https://github.com/Cog-Creators/Red-DiscordBot/blob/V3/develop/redbot/core/_cli.py#L26
https://github.com/Cog-Creators/Red-DiscordBot/blob/V3/develop/redbot/core/data_manager.py#L116-L121

### What actually happened?

The process will exit with error code 1 due to the following traceback:
```py

### How can we reproduce this error?

1. Install Red.
2. Configure an instance as you'd normally expect.
3. Attempt to launch the bot with `--no-prompt` without filling in token/prefix.
4. Check error code with `echo $?`.

### Anything else?

This process has been realized on Ubuntu.
