fix(dashboards-eap): Open in Explore passing aggregates as fields

[narsaynorath]

Fixes the Open in Explore flows from Dashboards. The main issue is that field shouldn't be populated in the query params unless we're setting columns for the sample mode, and they should not contain aggregates. The consequence of the previous behaviour is that aggregates would appear for individual samples in the samples view, which is not a valid state.

The following test cases have been updated

• Table with aggregates
  • Produces a URL to Aggregate Mode with the columns in the group by and aggregates in a visualize object
• Tables without aggregates
  • Produces a URL to Samples Mode with no grouping set and columns set in the field query params
• Charts do not add field to the query params
  • Charts by definition are plotting an aggregate, so put the chart in aggregate mode and the only columns that apply are in the groupBy param

Fixes EXP-177; The sorting is resolved because the user cannot get into a state in the samples table where the columns are not valid and therefore not properly triggering a request when the columns are clicked.
