Fix for Integer/FloatToolParameter.get_html_field() when 'value' is provided as an integer/float.

Fixes an issue seen when saving workflows: If an integer or float tool parameter is changed to a value of 0 or 0.0 and saved, the form field would be redisplayed using the default tool value; and not the value that is now saved in the database.
