mod_storage_sql: Handle failure to deploy new UNIQUE index Somehow a user ended up with duplicate data preventing creation of the new unique index needed for UPSERT (see 3ec48555b773). This should eventually self-heal #1918 if the duplicate data is replaced by the older DELETE + INSERT method. Without any index at all, it will be slower.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"prosody.util.compat".xpcall;
end

return {
	xpcall = xpcall;
};
