Fix error when executing method SSViewer::templates() when $subTemplates is still null

Without the fix this causes the framework to throw a 500 error:
`ERROR [Warning]: array_merge(): Expected parameter 2 to be an array, null given`

I noticed the error while doing a search with the `GridFieldAddExistingAutocompleter`. The error probably gets supressed on live environments.
