bump -avastalevotethreshold a bit because some rounds get voted while finalizing the first block

add test cases for all invalidated and all stalled contenders

fixing locking issues

3. Test case if all contenders are stalled.

rebase

skip if wallet isn't available

Avoid unused pollableContenders at call sites for now

Make local acceptance match what this node would eventually vote

Add comments to make it more clear that the test is checking the item is not being polled for

Remove erroneous image file change
