Tensor Init Bug Fix

[kylebd99]

Galley's tensor initialization is improper, leading to memory leaks between invocations.

This patch fixes that by updating the init to reference an expression rather than a tensor.

This looks good to me, can you verify that it fixes mateusz's issue?

[kylebd99]

Can confirm. Ran it with main and it crashes, ran it with this and it doesn't.
