Subject: [PATCH] [download-cache] Fixed init logic to skip when cache file is
 missing (#10362)

There are several possible causes of the cache file to not exist, including user
 action. By skipping these couple steps during initialization when the file is
 missing, a renew action is allowed to start and the cache will rebuild and
 hopefully work as expected.

Simple fix for #10360
