Problem continuing loading data in layer with Virtual Field

[minff]

Steps to reproduce:

1. Load a DataHub space into QGIS Layer
2. Create a Virtual field in the QGIS layer
3. Save and close the project
4. Reopen the saved project

Expected: The plugin shall continue loading data into the existing layer,

Actual: The plugin failed to load data, as there is mismatch between list of fields (properties) of QGIS Layer and DataHub space

Feature has too many attributes (expecting 7, received 10)
