Add a warning if the defined SQLite vault did not exist and was created on-the-fly

Is your feature request related to a problem? Please describe.
It's possible to put the wrong path to your SQLite file in the config, or move devine and cause relative paths to go to fritz.

Describe the solution you'd like
Warning the user if the .db file didn't exist yet when it loads the vaults would be a good idea.
Perhaps "The Key Vault '' was not found and a new one is being made.", proceeded by:
"Ignore this warning if this is the first time making this Vault.".

Describe alternatives you've considered
We could just stop further execution with a hard error, but then there's no way to make new vaults on the fly.
However, that could be a better solution overall. We could make a devine kv new command that can create a
new SQLite Key Vault at a specific path.
