Fix urlencode

[zrq495]

When the value has been urlencoded, it needs to be urlencoded again, not just replacing &.

Thanks @zrq495 ! Can you also add a test for this case ?

@zrq495 any updates on this? I need this fix ❤️

@ddascal @fbergero I am sorry. I had been trying to run the test, but i failed to make it.
I have been using it under my production and it proves to be accessible, so you can use it directly.
if it is convenient for you, you can add a test for this case.

@zrq495 is your build uploaded to luarocks?
Additionally this also escapes the topic ARN like

arn%3Aaws%3Asns%3Aus-east-1%3AXXXXXX%3Asometopic

That doesn't make a difference?

@fbergero Just build locally
I didn't notice ARN, does it not work properly?
