util.promise: Remove some redundant checks, add tests confirming redundancy This lines don't appear to do anything useful, and all tests pass when they are removed. Discovered via mutation testing. I added extra tests to exercise this code, because I wasn't certain that there were no side-effects caused by removal. Everything appears to be fine, thanks to the "pending" check at the start of promise_settle().

local record lib
	create : function (narr:integer, nrec:integer):table
	pack : function (...:any):{any}
	move : function (table, integer, integer, integer, table) : table
end
return lib
