typeahead: solve problem with potential long query parameter
- maybe a post request?
- Problem was #4009
- User loads form
- use typeahead against uzh webpass
- shortname as column
- user save and close record
- user open form with saved record again
- form loads
- typeAheadLdapSearchPrefetch: typeahead fires a query after form load to display expanded LDAP search query. for this it uses the expanded value. this is not clear to CR why.
- The expanded value exceeds the SECURITY_GET_MAX_LENGTH of 50.
