Apex CLI editor closes standard input/output/error

The Apex CLI editor closes its input and output when it completes. This is correct behaviour when the input and output are files. However, if the input and output are tied to standard input, output, and error then if there are subsequent actions in the JVM (Such as continuing to run Apex as we do in tests), then any output such as logging is lost.

This fix checks for standard input/output/error before closing the input
and output.
