Help swaps flakiness

[BrodyHughes]

Looks like a lot of changes but it's not really:

• wrapped the swaps flows in a describe wrapper, which makes the 'lines changes' really long, sorry
• added a few helpers to try and check exact transaction hashes by address to find the most recent sent txn by the test wallet, and see if the txn was successful. If not, it waits and checks again.
• this is better than some non-specific delays imo, and i think will help make the tests more consistent
• the two swaps flows were cut back several times, and so we were basically duplicating the entire test file to just swap USDC in the 2nd swap test. I instead just moved this to the end of the first test. This should make test times shorter, and hopefully help with flakiness by removing room for error
