Merge #16796: wallet: Fix segfault in CreateWalletFromFile

Browse Source 
fa734603b7 wallet: Fix segmentation fault in CreateWalletFromFile (MarcoFalke)
fab3c34412 test: Print both messages on failure in assert_raises_message (MarcoFalke)
faa13539d5 wallet: Fix documentation around WalletParameterInteraction (MarcoFalke)

Pull request description:

  Comes with a test to aid review. The test should fail without the fix to bitcoind

  The following `CreateWalletFromFile` issues are fixed:

  * `walletFile` refers to freed memory and will thus corrupt the debug.log and/or crash the node if read
  * `WalletParameterInteraction` was moved to `CreateWalletFromFile` and `WalletInit::ParameterInteraction` without updating the documentation
