Fix T58439: Info Editor does not show operator reports immediately when
operator cancelled.

Lots of operators return OPERATOR_CANCELLED when no data really changed.
Reports from those operators do not show immediately in the Info Editor
[they only do if the operator returns OPERATOR_FINISHED].

Now also notify the Info Editor in case of OPERATOR_CANCELLED.
