Subject: [PATCH] fix: if no keys, set number of translated to 0

If there are no string keys for a given key type (sim-specific, shared,
or common), we set the number of translated strings in the form to 0.

For https://github.com/phetsims/rosetta/issues/345.

Came out of https://github.com/phetsims/qa/issues/869.
