[FIX] pivot: add deferred calculated measure

Steps to reproduce:
- Open a pivot side panel
- click on "Defer update"
- add a calculated measure

=> boom

It's looking for the compiled formula in the plugin, but it doesn't exist
since the pivot was not updated yet.
It's ok to (re)compile the formula everytime in the side panel, it's only
one formula and it's not a hot path.

closes #7207
