p2p-autoinstantsend.py

Test automatic InstantSend locks functionality.

Checks that simple transactions automatically become InstantSend locked, 
complex transactions don't become IS-locked and this functionality is
activated only if SPORK_16_INSTANTSEND_AUTOLOCKS is active.

Also checks that this functionality doesn't influence regular InstantSend
transactions with high fee.
