LeAudioTestApp: Fix crash issue when starting broadcast 

getAllBroadcastMetadata will return immutable Collections.emptyList()
in error cases, this might cause following list add operation in
updateBroadcastMetadata report UnsupportedOperationException.

the fix is to use ArrayList instead if the broadcastMetadata list is
empty.
