SQL error after DB column escaping

[romanstrobl]

The column escaping introduced in https://github.com/wultra/powerauth-push-server/pull/859/files does not work properly on Oracle due to enforcing case sensitivity.

We should probably go back to the original solution which was renaming columns, which has no side effects, it only slightly complicates the migration to new release.
