Don't block users from exporting single certificates if they are able to export all certificates

[Ein-Tim]

Current Implementation

Currently, in some cases (f.i. if the user wants to export an EU DCC which was not issued by Germany) the user gets an error message that the app can't export this certificate. However, if the user then uses the export all feature, which was shipped with version 2.24, the user is able to export all certificates, including these where the app stated that an export is not possible.

Suggested Enhancement

Don't block certificate exports from single certificates if the user is able to export this certificate using the export all feature.

Expected Benefits

The user is not confused and it is easier to export the certificate. Also, this would add some logic to this part of the app :D
