Fix AdoNetAppender using npgsql once again.

[NicholasNoise]

Same bug as #71.
npgsql@4.1.9 (above 4.* in general) completely destroys adonet appender.

3.* fails to prepare command but allows to execute it.
4+ fails to prepare and to execute.

@fluffynuts 2.0.14 pretty please? :)

[fluffynuts]

LGTM; I have another small issue I'd like to include in a release, but not sure exactly when I'll get to it; hopefully sooner rather than later.

[NicholasNoise]

Thank you!
Patiently waiting for upcoming release

This seems to have broken AdoNetAppender with Microsoft SQL Server. I have no logged events in the database after upgrading from 2.0.13 to 2.0.14. Did you test it on a SQL Server?

[fluffynuts]

@dskantz no, I didn't, because I don't always have every possible database server installed. I believe I may have a fix in the pipeline, if I could allocate time to this. In the mean-time, I suggest downgrading to 2.0.13.

@fluffynuts, great! Ping me in the PR if you want me to try it out on SQL Server before you merge. Well, at least on 2019.

You could try a build from master if you're up for it. At least it could confirm or deny whether it's fixed. If not and you're really motivated, fix & pr 😀
