person_search_view should discard non integer lunaids

[WillForan]

maybe also make sure addId doesn't add text to lunaid

lncddb_test=# select * from enroll where id like 'test5';
 eid | pid | etype  |  id   | edate 
-----+-----+--------+-------+-------
   7 |   2 | LunaID | test5 | 

select * from person_search_view;

ERROR: invalid input syntax for type integer: "test5"
