Fix connection limit checks so as to prevent the following warning:

WARN b.n.p2p.peers.PeerManager: No candidates found to remove (That
case should not be possible as we use in the last case all
connections).

this might be a good opportunity to add a unit test for PeerManager (possibly limited to the scope of connection handling)

It seems the PeerManagerTest is ignored and in need of an overhaul.

Could someone of the exisiting contributors try out this branch before merging, as it would cause big problems if some use-case handling is wrong. I just read through the code and it looks fine, but it would be good to give this a local test as well.

I think that code part is really a good candidate for a test. The logic is a bit involved and bigger changes here are tough to test manually. I would postpone otherwise merge until someone had dedicated enough time to be sure all is correct.

Agreed. I will try to look into implementing some tests. Just not familiar with this area so will need some time to ramp up.

@devinbileck Are you still on this PR?

I started looking into it but didn't make much progress. I haven't focused on it very much lately. If someone else is able to contribute something, feel free. Otherwise I will try to get to it.

@devinbileck Could you please resolve the conflict and add some tests?
@freimair Could you review the code?

I have added some tests. I will be committing them shortly.

@devinbileck
Add PeerManagerTest
b45765f 
The old PeerManagerTest was located under network/p2p/routing, which is
no longer the correct location. Additionally, it was outdated so I
just removed it and added a new file under network/p2p/peers containing
tests for checkMaxConnections.
@devinbileck
Add testCompile dependency to core
21572ea 
This is necessary because bisq.network.p2p.MockNode imports
bisq.core.network.p2p.seed.DefaultSeedNodeRepository.

@freimair As I haven't touched this part of the codebase so far, could you please do the review? Thanks!

IMO we could get away with mocking the SeedNodeRepository superclass, thus eliminating the dependency to core. Can you verify that this is correct?
