Fix #14538
Fix crash attempting to load the same wallet with different path strings that resolve to the same absolute path. The primary check which prevents loading the same wallet twice is:
6b8d0a2164/src/wallet/db.cpp (L44)
But this check is skipped if both wallet paths resolve to the same absolute path, due to caching here:
6b8d0a2164/src/wallet/db.cpp (L467)
Meanwhile a secondary check for duplicate wallets is not reliable because it based on a literal comparison, instead of comparison using absolute paths:
6b8d0a2164/src/wallet/wallet.cpp (L3853)
This PR fixes the latter check to compare the absolute path of a new wallet being loaded to absolute paths of wallets already loaded, so there should no longer be any way to load the same wallet more than once.
