Title: Concurrency issue for the parser collection in StackTraceParser

By using Approvals in a MbUnit executing tests in parallel I discovered an issue in StackTraceParser that the initialization of the parsers collection is not thread-safe. I fixed the issue by using a static constructor, this way we ensure that the collection initialization is thread-safe.

I've also added a unit test.
