ZBX-11411 prevents ability to use items with macro parameters in calculated items

When using aggregate items that use usermacros to create a new calculated item, the input validation of ZBX-11411 prevents the evaluation of such items:

Using the following configuration:
Marco {$I_AGGR_GROUPNAME}: Routers
Formula: last("grpsum[\"{$I_AGGR_GROUPNAME}\",\"cell.int.usage[monthly]\",last"])/last("CellDataBundleSize")*100

We get the error: "Macro {$I_AGGR_GROUPNAME} value is not numeric"

This is probably true for other items that are using macros as parameters as well.
