Remove sequence-response handling dependence on message logging ON status

_Sequence handling does not work_, when Message Logging is turned off. In this case the responses are not collected to the sequences, and stub response generation is not possible.

This is because turning on/off message handling is adding/removing relevant processors by `com.epam.wilma.core.toggle.message.MessageLoggingToggle` class, but extracting and storing the sequence response is in the `ResponseQueueListener` class, that works only when the processor is enabled.

Need to remove the sequence-response handling dependence on message logging ON status - that feature should be always enabled.

Start by reading com.epam.wilma.core.toggle.message.MessageLoggingToggle and ResponseQueueListener to trace how processors are enabled and how sequence responses are collected. Confirm the behavior with Message Logging turned off, then verify that sequence responses are still stored and stub response generation remains possible independently of message logging.
