Investigate if withdrawable states marked correctly

[gusin13]

for the delegations that have been marked withdrawable, i am bit suspecting if this is happening correctly.
For example below delegation is withdrawable but the start/end height tells a different story. Most probably this is early unbonded but from the db there is no way to verify this
