reduce flakiness with cleanup tests

[rabi-siddique]

The PR does the following:

• Segregates tests related to closing vaults and canceling bids into a separate context.
• Removes 3-second wait when verifying auction data. Adding this wait did not bring any stability in the tests.
• Update the tests related to claiming collateral. Use a different selector and add new timeout values based on the consideration for a busy network.
• When canceling the bids that are not accepted, sometimes there is flaky behavior when switching to a new wallet. I've been inspecting this but not sure why that tends to happen. Switching the wallet in a separate test case solves the problem.
