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

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
