Functional tests of Command execution and projections

[agehrke]

This PR adds functional tests of Command execution and projections.

The concept is:

• Build a host with EventStore and CQRS - see CqrsTestHost.cs
• Replace IEventStoreClient with an in memory implementation (like the existing InMemoryStore) - the implemention in InMemoryEventStoreClient.cs actually works :)
• Commands are executed and side-effects asserted

Please give input on everything from style, placement of files, code design, etc.

The build failed with the following errors

You should get the same errors when building in release mode locally.

I do get the warnings in a debug build. I really don't understand the issue. The analyzer says that

error S3604: Remove the member initializer, all constructors set an initial value for the member.

How can this be true for reference types? Maybe I should upgrade the analyzer?

• The string literal "leasetoken" appears to be a typo. Consider renaming it to "leaseToken" for clarity.

await sub.ExceptionHandler("leasetoken", ex);

Ok, the issue is in SonarAnalyzer, so I have upgraded it and fixed two new issues:

• InMemoryStore.cs - Warning S6612 : Use the lambda parameter instead of capturing the argument 'name'
• ProjectionFilter.cs - Warning S6608 : Indexing at Count-1 should be used instead of the "Enumerable" extension method "Last"
