cc: Fix TestOptionsProvider image entries caching.

Right now TestOptionsProvider tries to intercept transfer cache usage
for images, which invalidates a lot of the assumptions made by the
calling code. Instead change this to create and store transfer cache
entries similar to production behaviour.

Also remove some asserts from TransferCacheTestHelper. Since this is
used by fuzzers, it should behave more like production code.
