Merge bitcoin#15247: qa: Use wallet to retrieve raw transactions

fa5278a qa: Use wallet to retrieve raw transactions (MarcoFalke)
fa21983 qa: Style-only fixes in touched files (MarcoFalke)

Pull request description:

  Instead of asking the coin database and block storage about a transaction, pull it directly from the wallet in wallet related tests.

  This refactoring only makes sense in light of bitcoin#15159.

  <sub>This product may contain minor stylistic cleanups
