MythMusic crash after new scan

[JYA]

Just upgraded a machine to use SG for MythMusic

Ran a scan, which contained less files than my local storage

Got a crash:

this patch fixes it:

For whatever reasons, getCurrentPlaylist()->getSongAt(x) returned NULL

MythMusic: fix a possible crash after scanning for music

MusicMetadata::getSongAt() can return NULL so guard against that.
Fixes #12200. Thanks to JYA for finding the problem.
