Append multiple events + ExpectedVersion.NoStream = bug

[shaan1337]

Describe the bug
Appending multiple events with ExpectedVersion.NoStream to a stream that doesn't exist or that has been soft deleted throws wrong expected version.

To Reproduce
Steps to reproduce the behavior:

1. Start an empty database
2. Write two events with expected version NoStream

var e = new EventData(Uuid.NewUuid(), "type", new byte[0], new byte[0]);
await client.AppendToStreamAsync("stream", StreamState.NoStream, new EventData[]{e,e});

3. Throws:

Unhandled exception. EventStore.Client.WrongExpectedVersionException: Append failed due to WrongExpectedVersion. Stream: stream, Expected state: NoStream, Actual version: 1

Both events are appended but the client throws the wrong expected version error.
The same behaviour can be seen with a soft deleted stream - the events are appended but the client throws an error.

Expected behavior
No error should be thrown.

Actual behavior
Wrong expected version error is thrown
