Merge bitcoin/bitcoin#29363: test: Fix CPartialMerkleTree.nTransactions signedness

Browse Source 
facafa90f7 test: Fix CPartialMerkleTree.nTransactions signedness (MarcoFalke)

Pull request description:

  It is unsigned in Bitcoin Core, so the tests should match it:

  aa9231fafe/src/merkleblock.h (L59)

  Large positive values, or "negative" values, are rejected anyway, but it still seems fine to fix this.

  The bug was introduced when the code was written in d280617bf5.

  (Lowercase `i` means signed, see https://docs.python.org/3/library/struct.html#format-characters)
