Michael Fabian 'Xaymar' Dirks 8bb1ca50ac obs-source-tracker: Also keep track of sources being renamed
When a source was renamed, obs::source_tracker did not use the new name and instead relied on the old name. This caused source lists with this feature to slowly degrade over time as sources were renamed, until libobs was restarted.

With this fix the renamed sources are now properly tracked, updating as expected.
