  [clang][Index] Fix the incomplete instantiations in libindex.

Summary:
libindex will canonicalize references to template instantiations:
- 1) reference to an explicit template specialization, report the specializatiion
- 2) otherwise, report the primary template

but 2) is not true for incomplete instantiations, this patch fixes this.
