gladcow 6da2837bdd InstantSend Integration tests (#2141)
* adjust `AddLocal` method only in regtest mode

* Create Masternodes in regtest

* sentinelping call for masternodes

* set externalip option for masternodes in regtest

* fix MNB relay during masternodes creation

* fix node_count naming

* instantsend doublespend

* decrease node restarts

* prevent spending masternode collaterals

* move long test to the test list start

* remove InstantSend spork sending

* remove spork-specific code

* fix checking double spend rejection
