Avoid ArrayIndexOutOfBoundsException with no args (#9393) 
The `null` check creates a new Array but always assumed a non-empty one which may lead to
```
java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0

...
```
Added a guard to prevent the exception. The flag will be useless anyway as we won't enter the for-loop in this case.

Appears to be introduced via #8743. Discovered while debugging #9389.

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.
