Revert "Disable tests for notouch builds"

This reverts commit 312152d09848f4069ce6bae6b644c5eb73a7fe6c.

Reason for revert: The underlying issue can be resolved in a separate
layer, so it's no longer necessary to disable these tests.

Original change's description:
> Disable tests for notouch builds
>
> These tests are currently expected to fail in notouch.
> In this CL I've disabled and left a comment pointing to
> the associated bug.
