This PR fixes creation on table.
With the recent optimization refactor, we now use a custom event to
trigger edit and soft focus mode on a table cell.
There's a specific case when we create a pending row to allow creating a
new record, where the custom event gets triggered before the cell
exists, so it cannot listen and put itself in edit mode.
The fix is passing down a new isPendingRow in the context, so the
identifier cell on a pending row can put itself in edit mode during its
first render.
