getTransactions returns transactions outside the given block range

[smartcontracts]

Describe the bug
The operator exposes an RPC call, getTransactions, that returns a list of transactions received by a given address during a given block range. The parameters to the call are:

1. address - string: Recipient address.
2. startBlock - number: Block to start querying from.
3. endBlock - number: Block to end querying at.

However, it seems that startBlock and endBlock are being ignored. For example, when I query transactions from blocks 0 to 10, I'm getting things back from block 18 and 21.

Steps to reproduce
Steps to reproduce the behavior:

1. Make a transaction to an address in block N
2. Query transactions for that address with endBlock < N
3. Get back transactions with block B > endBlock.

Expected behavior
getTransactions should only return transactions received by an address during the specified bounds.
