Subject: [PATCH] interval: Redefine some properties in MetaInterval class

The `play_rate` property invokes the underlying C++ `set_play_rate` method, which leads to a bug (#1202).
The property is now redefined to make it invoke the overriding `MetaInterval.set_play_rate` method instead.

Fixes #1202
Closes #1204
