UnidirectionalSequenceLSTMLayer's inferShape is wrong written!

[clay001]

file src/armnn/layers/UnidirectionalSequenceLstmLayer.cpp
the line 360, ValidateAndCopyShape function, if you do not pass the OutputSlotIndex param, the default will set the inferredShapes to the first outputSlot which is not correct, the real output should be the last outputSlot.

Can some body help me to check my concern?

Hello.

I have looked at this and I can see you concern but as of yet I've not found a way that this would cause a fault. By any chance, have you developed a unit test to highlight this problem?
