devnet - validator 01 and validator 07 are jailed unexpected

[jia57b]

Description and context

validator 01 and validator 07 are jailed unexpected

Steps to reproduce

Precondition: A test node still running but cannot generate blocks.

1. Reset devnet (singularity height is 600)
2. self-delegate to genesis validator 10^7
3. Run singularity test (the test stop validator01 story and geth process and not start the process after singularity)

Experienced behavior

validator01: jailed at 601 height validator07: confilct voting from height 01 after reset and jailed at height 06 block 1-15 timestamps are from the previous day.

Expected behavior

validaor01 should be jailed at 600+200 (slashing window). validaor07: not sure how it was affected by test node.

@jia57b Please check this issue and close if it has been resolved.

Tested the issue of validator01 jailed:

1. stop validator before 410 height, reset missed block as 0 at singularity, it's jailed at 791 height
2. stop validator after 410 height and before 600, it's jailed at 600 + 190 - missed block + 1 (since the missed block is counted at the next block)

Cannot reproduce the validator07 issue.
