[klee-stats] Use the last row inserted instead of the row with highest Instructions

Last `Instructions` is not a good identifier to retrieve the correct row.
For the default setup, KLEE will generate two entries with the same last instruction.
One before clean-up and one after clean-up (i.e. if states are terminated on halt).

Using `rowid` will select the last line.
