[FIX] website: remove autocomplete from inputs in page properties

Before this commit, on Chrome browser, the page url input and the
visiblity password input were autocompleted with the user's login and
password in the page properties options.

After this commit, they are no longer.

Regarding the url input page, it seems to be because Chrome considers
that the first text input located before a password input in the DOM is
a login input.
