Ability to rebuild an individual stream's projections

[malscent]

Issue: A bug was introduced that affected a severe minority of projections (600/3,300,000). The events needed fixed, and projections re-built. The current capability to rebuild an individual stream's projection requires the use of the Async Daemon, which can rebuild projections of a Type, but not specific streams.

Proposed Solution: Introduce a new method(s) that allow the refresh of a stream's projection directly. e.g: RefreshProjection(Guid streamId)

Found a work around. If you aggregate the stream, then call store on the session and save changes, the projection will be updated. I don't know if this satisfies all use cases, but it worked for us:

public async Task<T> RefreshProjection<T>(Guid StreamId) where T: class, IProjection, new()
        {
            if (StartSession())
            {
                T stream = await _session.Events.AggregateStreamAsync<T>(StreamId);
                _session.Store<T>(stream);
                await _session.SaveChangesAsync();
                return stream;
            }
            else
            {
                throw new UnableToStartSessionException("An error occurred while attempting to create session.");
            }
        }
