[10.0][FIX] web_x2m_options: Restore no limit on Search More...

As there is pagination behaviour on tree view level,
the limit should not be set as this could limit
result ids a little bit too restrictively. Some
records could be excluded and lead to a wrong
display behaviour in case of default filters.
