Description
Bug occurs when saving geojson file after deletion one or more fields in it. Instead of deletion of desired columns, only their names are deleted an not the data they had. Data in its turn is moved to the columns that are left, replacing existing data (to user it appears as columns that were supposed to be deleted were renamed and the columns that supposed to stay intact are deleted). So the attribute becomes totally corrupted.
Steps to reproduce:
1) Open geojson layer with at least two attributes
2) Enable editing on this layer
3) Open attribute table and delete one of the field (everything looks fine at this point)
4) Save changes
5 Behold attributes corruption in saved layer
