add test for creating .meltano folder on ephemeral deployments on Windows

Have a project that doesn’t have a .meltano directory due to it being a ephemeral deployment (ie files from the repo are copied every run)

To repeat

1. Create a folder with only a valid meltano.yml
2. Run meltano install
3. See “DB Connection Failed” Error during install due to systemdb not being available
4. Note that to replicate this you cannot have a .meltano directory already created. If it’s already created the systemdb will be created as expected

To fix I manually copy a .meltano/db file over

I thought we had an issue about this but I couldn’t find it 😕

@visch I’ve updated the title - want to take it and add it to your list?
