fix(ivy): don't throw when attempting to destroy a destroyed ComponentRef (#31022)

Currently in Ivy we throw when attempting to destroy a `ComponentRef` that has been destroyed, however in ViewEngine we didn't which can cause some tests to break. These changes remove the error to match ViewEngine.

These changes resolve FW-1379.
