streaming mode doesn't check blocks field on predicate spec

[MicaiahReid]

Describe the bug
A predicate spec has an optional field blocks: Vec<u64> where the user provides a specific list of blocks to scan. If some of those blocks are past chain tip, we have to go to streaming mode. However, streaming mode only checks for an end_block so that predicate will be evaluated against every block, not just those in the blocks array.

To Reproduce
Steps to reproduce the behavior:

1. Create a predicate with blocks field containing blocks that are past chain tip
2. Observe the scan completing and the predicate entering streaming mode
3. Observe the predicate being evaluated against every block instead of just those provided in the blocks list.
