Update `has*` / `lookup*` to have correct argument types.
Update `has*` / `lookup*` to have correct argument types.

We were already passing `SymbolTable` at each invocaton point, but the
types in the method signature still said `TemplateMeta`. I am unsure why
TS allowed that, but I figured it would be nice to get the right types
in there anyways.
