Conventions should not affect mongodb serialization

[Tolyandre]

Assume an application that uses Horarium have code like this:

 ConventionRegistry.Register("EnumStringConvention",
                new ConventionPack {new EnumRepresentationConvention(BsonType.String),}, t => true);

Such code can be used to adjust the application's MongoDB document, but accidentally changes Horarium's internal representation of enum Status. Jobs serialized with different conventions are not compatible.

This behavior discovered after #41 lazy MongoDB access. With lazy MongoDB access, the app has time to register conventions. That leads to different serialization with lazy and without lazy access.

PR sets Horarium's field names and types explicitly to always match default conventions.

Also, minor typos fixed.
