Before this commit, when someone was editing a password, the stored
password may not be the expected one by the user.
Steps to reproduce:
1. Open "Outgoing Mail Servers" form.
2. Set a password (e.g. "yop").
3. Save, then edit.
4. Add "y" at the end of the password field.
> Expected value: "yopy"
> Actual value: "***y"
This is due to the use of the char field formatter, which displays passwords
by replacing the characters with '*'. It is not necessary to do this in edit
mode, because it uses an input field of type 'password'. The browser
automatically hides the value of such inputs.
Any changes on a input field in edit mode uses the value of the input, so the
value of an password input should contain the password, without '*'.
This commit fixes the issue by using the formatter in edit mode for the input
of type 'password'.
