[FIX] web: Correctly transmit fields to the control panel

Before this commit, the "fields" object given to the control panel was
altered by the view (e.g. dashboard populates it with its aggregates).
As a result the control panel and its subcomponents had an altered
object with more or less fields than expected.

Now, the initial "fields" object is given to avoid such problems.
