test: remove internal error tests
6b90463 
These tests tested internal functionality in a way that bypassed
all code that could reach these cases. Testing code like this code
to be covered even though it might actually never be reached from
anywhere if public APIs are used. It gives a false feeling of safety
that some code works as intended while there is no guarantee that
it indeed works as it should.

Therefore it seemed best to remove all of these. The only thing that
should be tested is the raw functionality of the internal errors.

lib: move extra properties into error creation
c91023c 
This encapsulates the Node.js errors more by adding extra properties
to an error inside of the function to create the error message instead
of adding the properties at the call site. That simplifies the usage
of our errors and makes sure the expected properties are always set.

Why this change? I'd prefer to have it there.

I prefer it that way as well. The problem is that you may not use this before calling super() and we need the context to be able to attach properties to the error from within the function that constructs the error message.
