pod digests: multilingual document digests sorted

Fixes for three faults in the insert (.ssi) digests.
The key was the language captured from whichever path resolved the
insert. It did not change across the loop over languages, so
every language's inserts were filed under one language. The key is now
the language being digested, as the digest of the primary file above it
already did.
- digest is taken after the check that the file exists.
- digest is now taken inside the guard.
- non-pod path now correctly keyed on the document's own language.
