Fix the problem with array nodes with single elements not displaying the node name.

Array nodes in deploy result like runTestResult.successes, runTestResult.failures, and messages do not display the node name when they contain just one element.  The solitary element's name gets displayed as node name.  This is a php issue, which we get around by explicitly creating arrays for array nodes with single elements.
