Issue with Creating Override for Translation with an Empty String

[lgrabbert]

When I create an override for translation with an empty string for a language, the database stores an empty string in the Translation field. If I attempt to retrieve the translation and then add a string to it, I encounter the following error: "An exception occurred while executing 'INSERT INTO sitegeist_csvpo_domain_translationoverride (persistence_object_identifier, sourceidentifier, labelidentifier, localeidentifier, translation) VALUES (?, ?, ?, ?, ?)'". At this point, I am also unable to modify the translation. To use the translation again, I have to manually delete the entry from the Translation table.
