Title: Added the IF EXISTS clause on the delete form entries data

I have an extension that provides a field that does not create any entries data.

But since the FieldManager tries to delete the table when we remove the field from a section, I have to create an empty data table just to make sure that the FieldManager won't crash.

@nickdunn did the same thing in is "Publish Tabs" extension.

So adding the IF EXISTS to the drop SQL command will make this work better.
