Subject: [PATCH] Harden spork15 value to 1047200 when on mainnet (#2830)

This is a hackish version of https://github.com/dashpay/dash/pull/2824,
meant for 0.13.x only. The reason for this hackish version is that the
code has diverged quite a bit and its not worth the effort to backport
the hardening code.

Even though 0.13.x included a lot of fixes for sporks handling and syncing,
I still feel more safe with hardening the spork15 block height. If
something goes wrong with spork syncing (e.g. its slower then the first
DIP2/3 block arrives), the whole sync process will fail otherwise.
