Fixes #4197. Reading from the contract store is expensive, we introduced a read cache to avoid the worst cases - still the first time reading an element is expensive (accessing the MPT). We set an approximate cost of 20000 gas; here we adjust to 5000 gas - it should be enough to deflect misuse, but not too big making normal usage overly expensive.
