Update tests.sql replace square brackets and "." between schema and view

[danakee]

Replace square brackets with double quotes and insert "." between schema and view in setting of testview.

Result was [dbo.testview_123] will now be "dbo"."testview_123"

Happy to merge this but you'll need to create a unit test to capture the breaking behaviour first before it can be merged.
