Potentially missing attribute is_safe when instantiating a _WeaviateUUIDInt class

[tibor-reiss]

The sample app weaviate_v4.py from openllmetry is throwing following error: AttributeError: '_WeaviateUUIDInt' object has no attribute 'is_safe'

For details see traceloop/openllmetry#1929

There are ways to fix this in that repo, but I am not sure if that is the best approach. How about adding this line to the constructor of _WeaviateUUIDInt (https://github.com/weaviate/weaviate-python-client/blob/main/weaviate/collections/queries/base.py#L66)?
object.__setattr__(self, "is_safe", uuid_lib.SafeUUID.unknown)
This is also the default value when creating an UUID instance.

I made the proposed change locally, ran some tests, and it looked promising.
