[FIX] web: load more with progressbar load more

Be in a grouped kanban view with progressbar with limit 10:

- records 1 to 10 are loaded on a column
- do "Load more..." on a column => records 11 up to 20 are loaded
- do "Load more..." 2nd time => records 11 up to 20 are loaded
- do "Load more..." 3rd time => records 11 up to 20 are loaded
- ...

While in reality it should be:
- do "Load more..." 2nd time => records 21 up to 30 are loaded
- do "Load more..." 3rd time => records 31 up to 40 are loaded
- ...

This was caused by the progressbar reloading the column's group. This
set the loadMoreOffset to 0 thus forgetting the current state.

Without the change, added tests failed with:

 records of column are loaded => actual: "1,2,2", expected: "1,2,3"
