[FIX] web: Display boolean title in list views

Since commit 9fbb4fb, the `title` attribute is added
to list views `<td>`. The title value is given
by field utils formatting methods, according to the
field type. However, for boolean fields, the formatting
method does not return a string but a jquery element
(unless `forceString: true` is given as an option).
Hence, the displayed title is `[Object object]`.

After this commit, boolean fields do not have any title.
