BUG: Batch and epoch metrics under the test namespace are identical

[Blaizzy]

Describe the bug

Batch and epoch metrics under the test namespace are identical

Example runs:

• Epoch metrics: https://app.neptune.ai/common/tf-keras-integration/e/TFK-39687/all?path=metrics%2Ftest%2Fepoch%2F
• Batch metrics: https://app.neptune.ai/common/tf-keras-integration/e/TFK-39687/all?path=metrics%2Ftest%2Fbatch%2F

Reproduction

Here is a reproducible script:
https://colab.research.google.com/github/neptune-ai/examples/blob/master/integrations-and-supported-tools/tensorflow-keras/notebooks/Neptune_TensorFlow_Keras.ipynb

Expected behaviour

Log precise metrics at epoch and batch levels.

We get those metrics from TensorFlow, so cannot fix this on our side. Maybe this should be clarified with TensorFlow developers?

@twolodzko my bad actually. There is no bug.

I haven't touched TF issues since a few months ago and didn't prime my brain for this throwback

I ran a few experiments and found out I confused the two.
