erp5_simulation_fast_input: Solve Divergences dialog: Handle error when XHR'ing Solver configuration.

When user clicks on the radio button to Accept Decision for example,
Delivery_getSolveDivergenceDialogParameterFormBox is called (XHR)
and when it failed, the 'Solve Divergences' button was disappearing
and nothing was displayed to end-user.
