Remove unnecessary condition from `ss_marriage_germany_partner_local?`
Remove unnecessary condition from `ss_marriage_germany_partner_local?`

The `ceremony_type` check was useless for two reasons:

* This predicate is within a block that only applies for same sex marriages.

* The `ceremony_type` variable can never equal 'opposite_sex' (the
`opposite_sex` calculate block always returns a PhraseList) so the condition
will always be true.
