Wladimir J. van der Laan 71b4cf307b Merge #14180: qa: Run all tests even if wallet is not compiled
fac95398366f644911b58f1605e6bc37fb76782d qa: Run all tests even if wallet is not compiled (MarcoFalke)
faa669cbcd1fc799517b523b0f850e01b11bf40a qa: Premine to deterministic address with -disablewallet (MarcoFalke)

Pull request description:

  Currently the test_runner would exit if the wallet was not compiled into the Bitcoin Core executable. However, a lot of the tests run without the wallet just fine and there is no need to globally require the wallet to run the tests.

"""Test the wallet backup features.
Test case is:
4 nodes. 1 2 and 3 send transactions between each other,
fourth node is a miner.
1 2 3 each mine a block to start, then
Miner creates 100 blocks so 1 2 3 each have 500 mature
coins to spend.
Then 5 iterations of 1/2/3 sending coins amongst
themselves to get transactions in the wallets,
and the miner mining one block.
Wallets are backed up using dumpwallet/backupwallet.
Then 5 more iterations of transactions and mining a block.
Miner then generates 101 more blocks, so any
transaction fees paid mature.
Sanity check:
Sum(1,2,3,4 balances) == 114*500
1/2/3 are shutdown, and their wallets erased.
Then restore using wallet.dat backup. And
confirm 1/2/3/4 balances are same as before.
Shutdown again, restore using importwallet,
and confirm again balances are correct.
