Issue description

Currently there is a bug in the view conditions - until now the ID of a record was stored in the DB at "Value corresponds to..." - now it is the alias if an alias attribute was specified at the relation. If the language is changed in the mask, the display condition does not work if the alias of the relation is a multilingual alias.

The methods getFilterOptionsForDcGeneral return the set alias as key - but we need the id. This could be solved with https://github.com/MetaModels/core/compare/feature-aliasaware
