Subject: [PATCH] tools: dedupe property access in doc/type-parser

There is no need to get this property twice in this rather hot spot:
if there is no such key, the `typeUrl` will be `undefined`,
which suffices for the boolean check in the next line.

For consistency, `undefined` can also be made the default value.
