catbref a4e127c84a Added INDEX to speed up block orphaning.
NOTE: first startup after this commit can take a while due to building index!

SQL statement "DELETE FROM HistoricAccountBalances WHERE height >= ?" required
a full table scan and so was very slow on VMs/routers. This statement used by
HSQLDBAccountRepository.deleteBalancesFromHeight(), itself called during
Block.orphan().

Symptoms particularly evident during shutdown where above statement could take
upwards of 15 minutes on single-CPU, small-memory VMs!

Statement wasn't noticed before as slow-query checking wasn't involved.
Slow-query checking now applies to HSQLDBRepository.delete() and
HSQLDBRepository.exists() calls.

Added test for correct HSQLDB interrupt handling.

Fixed some typos.
