AdminGrid: Pagination the new row on a new page not working

[tschumpr]

Steps to reproduce
Steps to reproduce the behavior:

1. Go to Administration - Mandate
2. Ensure that the row count is such that the last page in the grid is completely filled (e.g. 10 rows with pageSize 5 or 10)
3. Click "Add mandate"

Expected behavior
The grid navigates to the page with the new row

Current behavior
A new row is added but the pagination moves to the second last page (e.g. new row is on page 3 but grid shows page 2)

Note
Pagination works perfectly if the new row can be placed on the last existing page (e.g. before 8 rows with pageSize 5, new row can be added to page 2 where already 3 rows are displayed)
