`--ksc-exceptions` does not produces exceptions with stacktraces for the `CompilationProblem`s
As was observed in #857, sometimes `--ksc-exceptions` flag does not produce exceptions as it should and instead only writes user-friendly message. It seems that exception is not printed when the error was produced from the [`CompilationProblem`](https://github.com/kaitai-io/kaitai_struct_compiler/blob/542b24124a95f5308df625d667f8776dd023c696/shared/src/main/scala/io/kaitai/struct/problems/CompilationProblem.scala#L13)
