Error 500 when opening bug details: Property or field 'appId' cannot be found

Next issue after #446 is fixed: When I want to look at one of the reported bugs, I get an error 500 with the following stack trace:

similar issues (`Property or field 'appId' cannot be found) also occur on other actions, e.g. when trying to delete a version.

Okay so in a past release method security wasn't working at all. It seems now it is active but not updated for current usage patterns so I guess I gotta make a bigger check

I can report the same issue on v2.0.0-beta04.

I found a great testing library (https://github.com/mvysny/karibu-testing) to replace vaadin testbench (which I had to remove in the past because I did not have access to a license anymore).

Implementing tests for all pages will take a while, but the specific issues mentioned here are tested and fixed now.
