stream-manager: Select new proper device even if sink or source of new data is set

stream-manager: Select new proper device even if sink or source of new data is set

In tizen policy, selecting device is performed in tizenaudio-policy
module. The previous codes skip selecting the device logic if sink or
source of new data is defined(probably aka default sink/source) in
somewhere before the codes. This patch set it regardless of this matter.

We need to be aware of this modification for possible issues regarding
it. If the skip logic is needed anyway later, we may put that in
another place.
