Fix hierarchy generator logs freezing app

[bjosttveit]

Description

Another attempt at mitigating the freezing caused by spamming the logs in a loop. This time it was caused by the hierarchy generator running in a loop, and since hooks cannot be used here, I changed the way it logs only once. Now, there are new functions window.logErrorOnce which will check a set for a key first, and only log if it is a new message. Additionally, I am now debouncing the redux calls by temporarily storing log messages in a simple array first, to prevent ever spamming so hard that the entire page freezes. If you accidentally use logError instead of logErrorOnce in a React component render function, it will not cause a state change immediately and should not cause a blocking loop freezing the page anymore (though the logs will get a lot of messages after a while).
