Some irrelevant thunks to fix

```
ThunkInfo
{ thunkContext = [ "ChainSyncState" ]
, thunkInfo = Just " :: @ :"
}
Use -p '/Select best chain when CaughtUp/' to rerun this test only.
```

```
ThunkInfo
{ thunkContext =
[ "JumpInfo (TestBlockWith ())"
, "Maybe"
]
, thunkInfo = Just "processJumpResult.lookForIntersection :: JumpInfo blk_a42AY @ ouroboros-consensus/src/ouroboros-consensus/Ouroboros/Consensus/MiniProtocol/ChainSync/Client/Jumping.hs:707:13-55"
}

Use -p '/With some adversaries.honest peers are synchronised/' to rerun this test only.
```

```
ThunkInfo
{ thunkContext =
[ "MeasuredWith"
, "StrictFingerTree"
, "unanchorSeq"
, "AnchoredSeq"
]
, thunkInfo = Just " :: @ :"
}

Use -p '/StateMachine.InMemV2/' to rerun this test only.
```

Start by rerunning the three named tests with their -p filters: Select best chain when CaughtUp, With some adversaries.honest peers are synchronised, and StateMachine.InMemV2. Inspect the reported ThunkInfo values, including processJumpResult.lookForIntersection in ouroboros-consensus/src/ouroboros-consensus/Ouroboros/Consensus/MiniProtocol/ChainSync/Client/Jumping.hs at lines 707:13-55. Done means the irrelevant thunk reports no longer appear in these test outputs.
