### Issue
I experienced a rare panic with the new filter code.
```text
panic: runtime error: slice bounds out of range [121:100]
goroutine 25311363 [running]:

### Resolution
1. Create a unit test reproducing the panic.
2. Ensure the slicing indices are calculated correctly and do not
produce an invalid range.
### Running the new unit test on unfixed code:
```bash
$ go test
--- FAIL: TestFilters_AddPendingTxs (0.00s)
--- FAIL: TestFilters_AddPendingTxs/TriggerPanic (0.00s)
filters_test.go:451: AddPendingTxs caused a panic: runtime error: slice bounds out of range [10:5]
FAIL
exit status 1
FAIL github.com/ledgerwatch/erigon/turbo/rpchelper 0.454s
