HM-3.4 dev RA decoding crashed

Description

When setting number of reference frame to 1, RA configuration, decoder crashed at picture 9. In my opionion, it was caused by the wrong reference frame setting at the encoder. e.g.
POC 9 TId: 0 ( b-SLICE, QP 36 ) 1880 bits [Y 30.6981 dB U 39.8979 dB V 40.6632 dB] [ET 2 ] [L0 12 ] [L1 12 ] [LC 12 ] [MD5:d30f5f1134b6520551eb1271df5e86be]
Actually picture 9 should use picture 8 and 10 as reference frame.
One way to fix this bug is to change TComSlice::decodingMarking in TComSlice.cpp around line 744 from
if ( rpcPic->getSlice( 0 )->isReferenced() )
to
if ( rpcPic->getSlice( 0 )->isReferenced() && rpcPic->getReconMark() )
Meanwile, it is better to do the same change for line 807.
