Remove old database migrations that seem to get always executed

[reckart]

Describe the refactoring action There are some database migrations that appear to be always executed. It seems at least some of them are removing indexes from ancient WebAnno versions that were created there when we still used Hibernate to maintain the schema. It would seem these migrations could removed now:

Need to check all of these migrations - there may be some with a different background/history.

Expected benefit Avoid running certain migrations every time the application starts.
