LibJS: Skip caching get_by_id() if object's shape is changed by a getter
Fixes a bug that reproduces with the following steps:
1. Create an object with a getter for property "a" in its prototype,
   where the getter adds an "a" property to the object itself.
2. Call the "a" getter in a loop for the first time. This triggers
   caching of metadata indicating that the "a" property is located in
   the prototype chain.
3. Call the "a" getter in a loop for the second time. Oops, the cache
   says the getter is in the prototype chain, but the object now
   also has its own "a" property that was added by the first getter
   call.
