Query save problem for env variable connection

[tommy-hansen]

(THANKS, for a very nice plugin!)

I ran into this on Windows. I have a single DATABASE_URL/DBUI_URL connection. Query-save failed and based on the error message it looks like save was trying to use the connection URL as a default folder name. (I wonder if it would it try to create a folder based on a URL that includes a password too?)

Maybe use some version of the env variable name as a default folder name? This would work with post-fixed variables it seems. I don't really care what the folder name is in this situation, as long as it reliably works and is safe.

Moving the connection to connections.json with a name worked around the issue but env variables are preferable in my case.
