Remove special handling for older TDS connections (#1275)

`tiny_tds` v3 will raise an exception when using a TDS version older than v7.3 for the server connections. This is mostly to enforce that people do no longer use `tiny_tds` with ancient SQL servers (and report issues). But therefore, we can remove a couple of special cases in the `sqlserver-adapter` tests where they behaved differently if ran against older versions.
