Merge #12949: tests: Avoid copies of CTransaction 

fae58eca93 tests: Avoid copies of CTransaction (MarcoFalke)

Pull request description:

  Avoid the copy (or move) constructor of `CTransaction` in test code, whereever a simple reference can be used instead.

Tree-SHA512: 8ef2077a277d6182996f4671722fdc01a90909ae7431c1e52604aab8ed028910615028caf9b4cb07a9b15fdc04939dea2209cc3189dde7d38271256d9fe1076c
