Type Handler registry collision warnings

When importing the `orbax` checkpointer, our scripts throw warnings as below:
```
WARNING:absl:Type handler registry overriding type "" collision on scalar
WARNING:absl:Type handler registry overriding type "" collision on scalar
WARNING:absl:Type handler registry overriding type "" collision on scalar
```

Since these are warnings I don't think there is anything particularly bad that needs remedying but we would like to remove the warnings for our logging.

A MRE is given below:
```python
from orbax import checkpoint as ocp

print("Testing the OCP warnings")
```

Is this an issue with how the global type registry is set up? Thanks in advance.
