Null parameter in function call which fails a verify does not produce a useful error message

If a function call is made on a Mock which takes a null parameter, which is then verified and fails, it produces a non-useful error message.

TypeError: Cannot read properties of null (reading 'hasOwnProperty')

 ❯ eval node_modules/@typestrong/ts-mockito/lib/utils/MethodCallToStringConverter.js:16:68

It looks like objectIsStringable() in src/utils/MethodCallToStringConverter.ts can't handle null values (including I assume undefined), since it tries to do arg.hasOwnProperty("toString"); if the arg is not an Object, which will immediately fail.
