fuzz: pass coins_view_cache to TestCoinsView in coins_view

Browse Source 
Refactor TestCoinsView() to accept the cache as a parameter instead of
creating it internally. This prepares for adding a CoinsViewOverlay
fuzz target that needs to pass in a different cache type.

This is a non-functional change.
