PR Checklist
For bug fixes / features, please check if your PR fulfills the following requirements:
What is the purpose of this PR?
As described in #217 the after_prepare script hangs with error
.forEach is not a function
. This happens either if there is only one plugin configuration in the config.xml or if a plugin configuration only has one variable. This is due toconfig.widget.plugin
orplugin.variable
not being arrays in this cases. This PR makes sure that both always are arrays.Does this PR introduce a breaking change?

Tested with different config.xml scenarios.
What testing has been done on existing functionality?
Tested with different config.xml scenarios.
Other information
