c16040aecc native: sort GetValidators result 
As it's returned sorted now. Fixes state change mismatch for
NextValidators. It also partially reverts
2f8e7e4d33 and significantly changes the test
chain as the fees are no longer being sent to the same account.

5ef08f60ae remove github.com/pkg/errors from dependencies 
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

d4c3a17883 interop/native: always use proper ScriptHashGetter, fix #924

7987cdadc0 native: update storage item value after gas distribution 
Even if the value is zero, the GAS distribution updates the balance height, so
storage item must be updated too. Fixes the followin on preview2 testnet:
block 74227: value mismatch for key ffffffff1454a6cb279fbcedc66162ad4ad5d1d910202b92743e000000000000000000000005: 1041032104809fd5002103f3210128010000 vs 1041032104809fd50021033f110128010000

e5f05790d5 core: cache standby validators in the Blockchain 
They never change, so it makes no sense parsing the keys over and over
again. It also simplifies the interface a little.

2f8e7e4d33 native: fix getvalidators to match C# implementation 
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.

Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.

It also affects tests as now the first validator is different and it receives
the network fees.

c7a040ff81 core: fix bug with native contracts methods initialisation 
`NewNEO()` and `NewGAS()` methods are trying to initialise
both `onPersist` and `incBalance` methods of NEO and GAS AFTER
nep5TokenNative is set to the VALUE of created nep5 token.
In this situation an attemmpt to call the corresponding native contracts
methods (e.g. transfer native GAS) leads to contract invocation failure,
as far as `nep5TokenNative.incBalance` method is nil.

Fixed this by initializing both `onPersist` and `incBalance` methods
before getting the value of nep5 contract.
