ignore cache on key name change, instead of crashing

In 6c2cf2ccdd7130a034e50f9bea481351d475a272, the names of some essential
data bits changed.  If those names are not in the tmp/apkcache, then
`fdroid update` shouldn't crash but instead just ignore that cache entry.
tmp/apkcache should be deleted since the metadata version was bumped, but
I guess that does not always happen.
