Closing detached HAF application triggers unexpected behaviour after restart

There is following scenario, that shows the problem.

• SELECT * FROM hive.app_create_context('ANY_CONTEXT')
• SELECT * FROM hive.app_next_block('ANY_CONTEXT') "returns FIRST/LAST"
• SELECT * FROM hive.app_context_detach('ANY_CONTEXT')
• Here app closes due to the crash, SIGINT...
• Trying to get new block: SELECT * FROM hive.app_next_block('ANY_CONTEXT') "error: Context ANY_CONTEXT is detached"
• Trying to attach: SELECT hive.app_context_attach('ANY_CONTEXT', FIRST-1) "error: Context ANY_CONTEXT has already processed block FIRST-1
• Trying to attach: second attempt: SELECT hive.app_context_attach('ANY_CONTEXT', FIRST)
• SELECT * FROM hive.app_next_block('ANY_CONTEXT'): "return FIRST+1/LAST". This is wrong because the FIRST block has not ever been processed and in this scenario has been skipped
