Title: HPCC-10310 ESP cores and restarts when invalid credentials are presented

Running Fedora, calling ldap_get_option(LDAP_OPT_ERROR_STRING) after submitting
invalid credentials results in a NULL string which is getting passed to strstr
resulting in a core in ESP. This change first checks if there is a valid string
before calling strstr
