Item label contain {item="sumSeries()", item_key=""} when doing expressions

[Thorsieger]

Describe the bug
Alias of items are not correct when doing expressions. It contain after the name of the expression a json item based on the source query for example :

{item="sumSeries()", item_key=""}

Expected behavior
Alias should only be the expression name, or the value set by setAlias()
