Creation of custom column, can lead to errors, when multiple Apps are created

[Backfisch145]

CC = Custom column

When creating a CC in App A, App B doesn't load if it cant find the CC there too.

The Ui doesn't show the CC but in the Background this exception is thrown:

org.springframework.jdbc.BadSqlGrammarException: jOOQ; bad SQL grammar [select `report`.`id`, `report`.`android_version`, `report`.`date`, `report`.`phone_model`, `report`.`marketing_device`, `report`.`installation_id`, `report`.`is_silent`, `report`.`exception_class`, `report`.`message`, `report`.`version_code`, `report`.`version_flavor`, `report`.`bug_id`, `report`.`custom_BUILD_CONFIG.BUILD_TYPE` as `CUSTOM_COLUMNS.custom_BUILD_CONFIG.BUILD_TYPE`, `report`.`custom_CUSTOM_DATA.User` as `CUSTOM_COLUMNS.custom_CUSTOM_DATA.User` from `report` use index (`IDX_report_date`) where `report`.`app_id` = ? order by `report`.`date` desc limit ? offset ?]
.
.
.

Caused by: java.sql.SQLSyntaxErrorException: Unknown column 'report.custom_BUILD_CONFIG.BUILD_TYPE' in 'field list'

My current workaround is, creating the same CC in both Apps.
