* restore from multiple mints

* disable profiler

* make format

* failed POST /mint do not increment secret counter

* store derivation path in each token

* fix tests

* refactor migrations so private keys can be generated by the wallet with .with_db() classmethod

* start fixing tests

* all tests passing except those that need to set a specific private key

* bip39 mnemonic to seed - with db but restore doesnt work yet with custom seed
