Subject: [PATCH 1/4] fix(storage): segfault during database migration
The `akonadi-db-migrator` tool reproducibly crashes with a segmentation
fault (or a failed assertion if built in debug mode) while executing
`prepareDatabase()` on the destination configuration.
The root cause is that both `DbInitializer` and `DbUpdater` expect
`SchemaVersionTable` to be populated. This assumption is not met by a
freshly created destination database: the table itself exists, but it is
empty at this point. Consequently, `SchemaVersion::retrieveAll()`
returns an empty list and the subsequent attempt to obtain its first
element triggers an out-of-bounds read.
Fix the issue by checking for an empty result list in both places.

Subject: [PATCH 2/4] fix(dbmigrator): remove leftover entries in
`db_migration` directory
This avoids potential issues when `db_migration` already contains a
stale database created with an old schema version.
