Fix T41950: Parent-Child Menu behaves weird

Issue was, parenting with operator, then unparenting would keep the inverse parent matrix.
So if you then parented again through the mere Object field of Object buttons, you'd still
use previous inver parent matrix, giving some weird behavior from user PoV.

This commit simply makes sure inverse parent matrix is always reset to indentity when clearing
parents.
