core, core/rawdb: optimize transaction indexing

Browse source 
In comparison to the original code snippet, my proposed solution adjusts the indexing target to head+1 instead of *tail. This ensures that the transactions are indexed from block 0 to the current head, excluding the head block itself.

This could be a more effective adjustment, includeing all the required blocks.
