Bug 9954 - CVS profile encoding not selected in edition

When editing an existing CSV profile, its encoding is not selected in combobox, first value "ascii" is always selected.

This patch corrects this (surely appeared with TT conversion) and also the fact that "uft8" is by default selected in creation form.

Test plan:
- Go to Tools/CSV Profiles
- In "New prodile" tab
=> Check that "uft8" is selected
- Create a new profile by entering name, an encoding (other than the first), and MARC fields
- Click on "Edit existing profile" tab
- Select created profile
=> Check that specified encoding is selected
