Always print stacktrace to provide some guidance of what is going on (#6128) 
Avoid displaying just `Execution finished with an error: java.lang.NullPointerException` without any additional detail.

# Important Notes
When there is an execution error outside of Enso code (identified by the fact that all stack frames belong to `java` language), let's print the whole stack rather than printing nothing. To simulate one can:
```diff
diff --git engine/runtime/src/main/scala/org/enso/compiler/Compiler.scala engine/runtime/src/main/scala/org/enso/compiler/Compiler.scala

The Enso Engine

The Enso engine is the codebase responsible for compiling and executing Enso code, as well as providing language server functionality to users of the language. It is subdivided into two major components:

  • Language Server: The Enso language service.
  • Polyglot API: The truffle-boundary safe API for communication between the language server and the runtime.
  • Runner: The command-line interface for Enso.
  • Runtime: The compiler and interpreter for Enso.
