Fix widget recovery init bug

Fix widget recovery init bug

chown is unnecessary for widget db initialize logic and
default user is not created yet when widget db recovery logic
is started. So chown logic for default user could cause failure
of widget db initialize logic. We need to remove chown logic
from widget db initialize logic.
