Increase more SignalR Java client test timeouts

[halter73]

@BrennanConroy It looks like the 1 second timeouts snuck in shortly after #25639 was merged. We should stick to 30 second timeouts for now on.

Addresses #25928

Note to self: Be careful to remember to undo the addition of the Ignore attribute that will be added by #25932 before merging

Yep, anything new is using the 30 seconds, but everything before that change went in has to manually be changed to 30 and that's easy to forget. So a couple things might slip through.

Wow, my UI lagged when VS opened at the same time as trying to click comment

@halter73 I merged my quarantine PR so you may need to rebase this to remove the "Disabled" attribute

@halter73 should we port this change to rc2? One of the builds there failed with a timeout: https://dev.azure.com/dnceng/public/_build/results?buildId=819720&view=ms.vss-test-web.build-test-results-tab&runId=26089948&resultId=100607&paneView=debug

Sounds like a good idea. I approved your PR.
