Subject: [PATCH] fix: use toBlock sources in preload

When indexing multiple sources we start from lowest block possible.
For example, if we index ContractA from block 1000 and ContractB from
block 2500, and preload step would be 1000 blocks we would preload as
such:
1. (1000, 2000) with sources [ContractA]
2. (2000, 3000) with sources [CotnractA] - because we look at sources
   from 2000.

With this fix we will actually use end-blocks sources so this won't
happen.
