[ci] make ci green again

[agryaznov]

recent PR broke merging ci jobs, let's fix it

[dvc94ch]

the reason is that multiple ci runs may be happening concurrently on the same machine, so no test/ci-run can use a fixed port number...

current issue

seems to be introduced here

docker build -t chronicle -f ./config/docker/Dockerfile.chronicle-release --build-arg PROFILE=testnet --build-arg FEATURES=testnet,develop .

@4meta5 would you please fix it? (for some reason that job wasn't run at the time of your merge, but it definitely was broken at that time)

@FlorianFranzen is removing the migration to fix it, it is weird because it compiles locally for me and the files and declarations are there

[FlorianFranzen]

Removed any migrations that were no longer needed (including the one bracking chronicle image builds).

Should be ready to go. Will merge it once CI passes.
