Remove legacy derivation paths
Note: this is a 'breaking' change for edge case wallets that could exist in the wild. This type of edge case wallet would need to have been created a couple of years ago and then never used until after this diff lands. In this case, the user may have funds on Path145 and/or Path245 but not Path1899.
Judgment call that this edge case can be safely ignored. This diff will not cause such users to lose funds.
This is not strictly related the the other diffs in this stack. However, dev decision that it is best to limit the amount of times we require all Cashtab users to migrateLegacyWallet.
