UMLR — Receptions should be redefinable elements as operations are.

Both Operations and Receptions are Redefinable Elements. However, not we cannot redefine Receptions. This is caused because query isConsistentWith() specifies where we can redefine them or not. By default, this value is "False" and for operations, the value is set to "true", but for Receptions, the value is not specified, which means it is "False".
We should make Receptions also redefinable elements as Operations are, which requires to specify isConsistentWith() query with "True" value.
