LP#1788680 prevent copy template apply failure on null stat cats

Under some circumstances, the current code can result in a JS failure:

Cannot read property 'filter' of undefined

When this happens, the copy template may apply partially or not at all.
This change simply makes sure cp.stat_cat_entries() exists before
attempting to filter it.
