Re-enable operator-uninstall.spec.ts

Business Automation Operands fail to load in uninstall operator modal. With "Cannot load Operands. There was an error loading operands for this operator. Operands will need to be deleted manually..." alert message.

"Delete all operand instances for this operator__checkbox" is not shown so the test fails.
