Build fails after latest commit in master

Hi @kozyilmaz

Looks like the latest commit in master broke the build.

Using the rex4539 branch you created for me.

Hope it's an easy fix :)

consensus/upgrades.cpp:72:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]

@rex4539 sorry for the delay, can you give it a try? enable-werror in build script is causing a lot of trouble for macOS and this is the first one. I removed enable-werror but also I'll go over all warnings and submit PR's along the way.

Compiled! Thanks again :)
