NIFI-15739 Added Expression Language validation to ExecuteGroovyScript dynamic properties and a session.get() in the onTrigger method to ensure there is a FlowFile to send to failure.

[dan-s1]

Summary

NIFI-15739

• Added Expression Language validation to the dynamic property creation in ExecuteGroovyScript to ensure users enter a valid Expression Language statement.
• Added a session.get() to the ExecuteGroovyScript onTrigger method when the "transfer to failure" failure strategy is chosen in order to ensure there is a FlowFile to send to the failure relationship when an exception is thrown before the script is executed.
• In ProcessSessionWrap, changed from session.commit() to session.commitAsync() in order to avoid a java.lang.RuntimeException thrown by MockProcessSession for using session.commit()`.
