Documentation for searchlogs is incorrect

[ripply]

The online documentation for searchlogs as well as the command line documentation is incorrect for the topics parameter - "null" is incorrect and it should be null

The online documentation's example also needs to be updated as well
https://docs.qtum.site/en/Qtum-RPC-API/#searchlogs

Expected behavior

searchlogs fromBlock toBlock ( "address" "topics" minconf )

Search logs, requires -logevents to be enabled.

Arguments:

1. fromBlock (numeric, required) The number of the earliest block (latest may be given to mean the most recent block).
2. toBlock (numeric, required) The number of the latest block (-1 may be given to mean the most recent block).
3. address (string, optional) An address or a list of addresses to only get logs from particular account(s).
4. topics (string, optional) An array of values from which at least one must appear in the log entries. The order is important, if you want to leave topics out use null, e.g. [null, "0x00..."].
5. minconf (numeric, optional, default=0) Minimal number of confirmations before a log is returned
