Panic: empty value in filter

[saimikiry]

Hi, devs! Using an empty value in "rules/ldapsearch/filter" will cause the program to panic (looks like: #709).

ldap2pg.yml

postgres:
  ...

rules:
- description: "..."
  ldapsearch:
    base: cn=admin,dc=test,dc=com
    filter: # empty (panic)

Expectations

Apparently, this exception is expected to be handled gracefully and not cause panic.
