[Download] Fixed download initialization

When many downloads are taking place one after another it was possible
that uninitialized memory used for state value has a 5,6,7 status, which
caused that web api interpreted it as not valid state change, when the
'DOWNLOADING' state comes. Now this should not occur as the state is
initialized before starting a download.
