Anna Shaleva 7c6cdcbcc9 core: fix bug with policy.MaxVerificationGas 
In 121c9664b we should take into account isValid flag of
NativePolicy contract while retrieving MaxVerificationGas native
policy value. Otherwise we won't be able to get MaxVerificationGas
after the node was restarted, because this value is not truly
stored along with the other native policy values.

This commit fixes bug with headers verification after the  node
restarting with an existing storage:

```
