[PATCH] bitbake: fetch2/npmsw: Check if there are dependencies before trying to fetch them

[belouargamohamed]

From: BELOUARGA Mohamed <m.belouarga@technologyandstrategy.com>

When there are no dependencies, _foreach_proxy_method does not verify that there are
dependencies to fetch before fetching them.
