Numbers of 'totalLocked', 'totalStaked' and 'totalSelfStaked' are wrong

[punkrock]

Actual behavior

I checked /api/v3/network/statistics on two different service nodes and both give totally different numbers even if both service nodes are on the same blockchain height. Please compare these numbers. Both nodes use the same versions of Core and Service (Core v4.0.0-rc.3, Service v0.7.0-rc.1):

Expected behavior

Numbers should be (almost) the same but not be different like in the examples above.

Steps to reproduce

Compare: https://testnet-service.liskscan.com/api/v3/network/statistics
With: https://lisk-testnet-service.punkrock.me/api/v3/network/statistics

Which version(s) does this affect? (Environment, OS, etc...)

Liskscan.com: Debian, Core v4.0.0-rc.3, Service v0.7.0-rc.1
punkrock.me: Ubuntu, Core v4.0.0-rc.3, Service v0.7.0-rc.1

Should be fixed with the fixes in PRs #1692 and #1896.
