[FIX] web: missing pivot measures when using favorites

Steps to reproduce
==================

- Go to budget analysis
- Switch to the pivot view
- Unselect the first three measures
- Save the current search and set it as default
- In the measures dropdown, there is only two measures remaining

Cause of the issue
==================

- When `context.pivot_measures` is used, the measures are computed from
  it and those that comes from the metaData are missing.
