Bugfix: Empty pre-filled value in auto-budgets
Bugfix: Empty pre-filled value in auto-budgets

The auto-budget pre-filled is empty when the set amount is above
1000 (view /budgets/edit/X).

The root cause was the function 'number_format' returning a string that
cannot be casted to a float when the amount is above 1000, because of the
thousands separator.
