System.MemberAccessException if enricher has static ctor

[Tolyandre]

If a custom enricher has a static ctor, configuration throws System.MemberAccessException : Type initializer was not callable.

There is how I discovered such behavior: Tolyandre/serilog-throw-context-enricher#2

To reproduce with a unit test:

1. add empty static ctor to DummyThreadIdEnricher
2. run test EnrichWithIsAppliedWithCustomEnricher

Actual behavior: test throws
Expected behavior: enricher is instantiated
