Log Message:
-----------
Fix incorrectly deleted elements in array modifier caps.

Add check for merging vertices into vertices that are themselves
marked for merge, was already done for array eleements but not end
caps.

Fixes bug [#31695] Array Modifier: End Cap fails if all vertices are merged

Also corrected some reversed assert arguments.
