Fixed reporting action states when restart page appears outdated

Browse Source 
If start buffer is more recent than restart, we update committed LSN
with last record LSN of block (last_end_lsn) while applying action but
forget about it while printing records with -f for investigation
purpose.

Note that while applying actions we use start_buffer to calculate
latest page out of block 2 and block 3 and then from latest take
committed LSN. For -f we don't need buffers so we just compare
directly with committed LSN from restart.
