Subject: [PATCH] schema: handle typedefs without a parsed signature

The tree-sitter parser emits parsedSignature: null for typedefs and
typeset members that aren't function signatures, such as
`typedef Address = int`, matching Option<TypeSignature> in libschema.
The TS schema typed it as always present, so searching a bundle with one
threw on `.arguments`.

Type parsedSignature as nullable and index only the name when it's null.
Bumps the schema to 0.1.19.
