Method update on Visual does not work when all fields are removed from dataview

[koureasstavros]

When adding or removing fields into/from dataview the update method triggers as expected but when the last field is removed from dataview the update method does not trigger.

Tested using the following specs:
powerbi-visuals-api: 5.4.0

Tested on the following environment:
Custom Visual for PowerBI using TypeScript provider for rendering
*When Custom Visual is using R provider then the r script is triggered even on last field removal
