Dump values in LiteKd UniqueList methods

Currently adding integer values to UniqueList creates them as integers, but removing looking for them as strings leads to broken functionality.

I tried to fix Github Actions for this one, but unsuccessfully.
@oldmoe if you running Actions on your personal server, you are at big risk. Look here. I was able to change your Action configuration by just opening PR.

Thanks for the fix, I am not running Github actions on my personal server, I need to get around to fixing those eventually
