[FIX] website: fix autocompleteWithPages option

Since the PR [1], the function autocompleteWithPages does not receive
a widget anymore and does not trigger an event on it when an url is
selected. Instead it is replaced by an optional function property
"urlChosen" which is called if given.
The error is that the optional check is wrong. The check is done on
the "options" parameter, not on its optional property "urlChosen".
This commit simply fixes this check.
