  Log Message:
  -----------
  Fix multi-segment paths in included templates

The <ref> elements with more than one segment (e.g. `extension/abc`)
stopped working in scenarios with object template inclusion in 4.6.
This is now fixed.

(Also, some obsolete test files were deleted.)

This resolves MID-8351.

(cherry picked from commit a0ca3252d90f0db40d7e086becbbe17f703023c6)
