Updating Instruction name directly doesn't update its ideal gate

[YonatanGideoni]

Bug description

When updating an Instruction's name its ideal gate isn't updated, leading to inconsistencies.

To Reproduce

from examples.single_qubit_experiment import create_experiment

exp = create_experiment()
print(exp.pmap.instructions['ry90p[0]'].get_ideal_gate(dims=[2]))

Expected behavior

Should print:

[[ 0.70710678+0.j -0.70710678+0.j]
 [ 0.70710678+0.j  0.70710678+0.j]]

Real output:

[[0.70710678+0.j         0.        -0.70710678j]
 [0.        -0.70710678j 0.70710678+0.j        ]]

(rx90 gate it was deepcopied from)
