Ava Chow f43571010e Resolve guix non-determinism with emplace_back instead of push_back ...

For some reason, building x86_64-w64-mingw32 on x86_64 and aarch64
results in a single instruction difference which can be traced down to
prevector.h:174. The ultimate caller of this is the copy constructor for
a prevector that ends up being called by std::vector::push_back in
walletmodel.cpp:183. By replacing the push_back with an emplace_back,
somehow this non-determinism goes away.
