When reading an object ID via `get_oid_basic()` or any of its related functions we perform a check whether the object ID is ambiguous, which can be the case when a reference with the same name exists. While the check is generally helpful, there are cases where it only adds to the runtime overhead without providing much of a benefit.
Add a new flag that allows us to disable the check. The flag will be used in a subsequent commit.
