[FIX] test_main_flows: use input tag

In some cases, the edit mode on the production form view is not already
rendered when hte tour try to write '1' in the qty_producing field. This
lead to a fail of the Main Flow Tour.

This commit specifically trigger the input tag to be sure the text will
be inserted in edit mode.
