Can't create mssql_odbc Data Source

[susodapop]

Issue Summary

An attempt to create an ODBC Microsoft SQL Server connection returns a HTTP 400 Bad Request error.

Steps to Reproduce

I use the API here to avoid any unintended connection tests.

curl --request POST \
  --url https://app.redash.io/<slug>/api/data_sources \
  --header 'authorization: Key <your api key>' \
  --data '{
	"name": "Test",
	"type": "mssql_odbc",
	"options": {
		"server": "server.example.com",
		"user": "user@server.example.com",
		"password": "password",
		"db": "example-db"
	}
}'

Returns:

{
  "message": "The browser (or proxy) sent a request that this server could not understand."
}

Checking Redash's logs it looks like an IntegrityError on line 155 of handlers/data_sources.py but I can't debug it past that.

Technical details:

• Redash Version: v9 Alpha
• Browser/OS: FF
• How did you install Redash: SaaS / preview-instance

I'm not able to reproduce this behavior anymore, actually. Seems to be working again normally.
