Try to stop running tray when version check fails

Move kill running tray process to version fix function
it should have been here all along, we can only expect a running tray
when there is one available, and only when it is available and the
versions don't match we need to update the version in which case we'll
have to stop the running tray, in normal case when fixTrayBinaryExists
is called, it'll most probably not have a running tray, as that binary
doesn't exist yet
