--TargetOutputLayerSet=<intermediate OSLs> fails to decode

[iole.moccagatta]

VTM fails to decoder when using --TargetOutputLayerSet set to intermediate layers of spatial scalability streams.

Example:

SPALSCAL_A_Qualcomm_1 located in /jvet-site/bitstream_exchange/VVC/under_test/VTM-incompatible
NOTE: this stream is decodable by VTM8.0 + MR1489. MR1489 has been merged.

Spatial scalability with noncontinuous 3 layers 0, 30, 50.

Decoder fails with --TargetOutputLayerSet=0 and TargetOutputLayerSet=1. Decoder decodes correctly with --TargetOutputLayerSet=2. Details bellow

Can't reproduce issue with current master and SPATSCAL_A_Qualcomm_3
