When database is shutting down header page should be fetched and next written to database in order to update transaction numbers. If AST, causing change of encryption state, arrived during DB shutdown right before TRA_update_counters() database encryption manager is already missing environment required to load encryption plugin (like attachment) and segfaults happens when plugin is tried to be loaded.

Update of DB header does not require presence of database crypt plugin - it's anyway not encrypted page. Therefore fix is ti check environment before attempt to load plugin.
