fix(inputs.sqlserver): SqlRequests include sleeping sessions with open transactions

example: Fixed an off by one error in counter variable in type FooBar.

SqlRequests did not include sleeping sessions with open transactions. This can make troubleshooting slightly problematic in some cases, where you see a blocked SPID but you don't see how long the blocking session has been sleeping. This fix will allow tracking sleeping sessions that keep transactions open.

makes sense to me, but I'd like to have also the opinion of @dimitri-furman as this will be implemented also for the Azure part

This is a useful change for all flavors of SQL.
