Handle cases when user cert database has NULL slots

The slots can be NULL if the user's username hash is empty string (e.g. in retail mode)

BUG=349085,340505
TEST=
Retail mode does not immediately restart (i.e. no crash).
In retail mode, go to chrome://settings/certificates -> buttons for importing certs should be disabled
