	Calls 'f' for every move in a string ending with 'moveId'.
	
	Parameters:
		moveId - id of the last move in a string.
		columns - list of columns to select from MoveDataCargoTest table.
			      Should not contain 'parent', it is selected by default.
		f - function that will be called for every move in a string, including last.
			Takes 1 parameter: move - table containing key-value pairs (column name -> column value).
	
	Throws:
		- if there is a cycle in a string (2 moves reference each other and etc.).
