I think the log message should reflect if we are leaving the label or adding it.

bots/csr/src/test/java/org/openjdk/skara/bots/csr/CSRBotTests.java line 168:

Is this a check for if the bot added the label automatically?

bots/csr/src/test/java/org/openjdk/skara/bots/csr/CSRBotTests.java line 172:

Adding the label here has no effect.

bots/pr/src/main/java/org/openjdk/skara/bots/pr/CSRCommand.java line 81:

I'm not sure this is a good idea. The only reason to keep the /csr command around would be to have a way of manually correcting the state of a PR if the bots somehow fail, but I'm leaning towards just removing the command. If a CSR is already linked in JBS, but is later deemed to not be needed, I think the user should fix that in JBS rather than through a Skara command.

I think this needs some discussion and input from more people.
