Bug fix: when enabling 'heatup_using_network_decisions', we should add the configured noise (#162)

Browse Source 
During heatup we may want to add agent-generated-noise (i.e. not "simple" random noise).
This is enabled by setting 'heatup_using_network_decisions' to True.  For example:
	agent_params = DDPGAgentParameters()
	agent_params.algorithm.heatup_using_network_decisions = True

The fix ensures that the correct noise is added not just while in the TRAINING phase, but
also during the HEATUP phase.

No one has enabled 'heatup_using_network_decisions' yet, which explains why this problem
arose only now (in my configuration I do enable 'heatup_using_network_decisions').
