[FIX] web: list: do not crush text fields

Before this commit, it might happen that text field columns in list
views were completely crushed, to let space to the other columns.

This commit fixes the issue by preventing text fields from being
wrapped during the ideal column widths computation. Doing so, text
fields will take space they deserve according to their content.
They will then be wrapped if necessary, so that they aren't trimmed,
unlike e.g. char fields.
