Call InitializeCurrentBlockTip and activeMasternodeManager->Init afte…

…r importing has finished (#2286)

While importing, IsInitialBlockDownload always returns true, meaning that
the call to UpdatedBlockTip will also receive true as fInitialDownload.

UpdatedBlockTip is never called again unless a block is mined.
Mining of new blocks in regtest however only starts after mnsync has
finished, which will never happen as it waits for the next call to
UpdatedBlockTip.
