Default config (test) - Wipes out existing secrets.yaml

[CCOSTAN]

Home Assistant release (hass --version):
0.59.2

Description of problem:
while testing, I disabled my configuration.yaml to generate a new default config and it replaced the existing secrets.yaml file.

Expected:
I don't think it should replace existing files. Especially that one. :)

1. rename/delete your configuration.yaml
2. restart hass
3. start restoring your secrets.yaml because it will be replaced.

Additional info:
Maybe a rename of that file to .old? I think there are plenty of scenarios where this could happen accidentally.

Looking at the code, it appears this will also wipe out the groups.yaml, automations.yaml, scripts.yaml, and customize.yaml files.

I'm working on a PR now to change this behavior
