## Motivation for features / changes
A recent change in Keras broke these tests. I believe it's related to
keras-team/keras#19805, which caused a name change in the names of the
nodes in the graph, but not too sure.

## Technical description of changes
Updates the affected test, but leaves it commented out, because when
this code is imported into the internal repository on our side, before
the keras update does, our project would break, as the keras change
would not be synced internally yet.
Once this is sycned to our internal repo, and keras is able to sync
theirs (without breaking us), we can enable the test and it should work
fine.

## Screenshots of UI changes (or N/A)
N/A

## Detailed steps to verify changes work correctly (as executed by you)
Ran tests with keras-nightly before and after the change, and they pass.
Then commented out the test for the reason noted above.

## Alternate designs / implementations considered (or N/A)
