bf36a3ccc212ad4d7c5cb8f26d7a22e279fe3cec gui: Fix race in WalletModel::pollBalanceChanged (Russell Yanofsky)
Pull request description:
Poll function was wrongly setting cached height to the current chain height instead of the chain height at the time of polling.
This bug could cause balances to appear out of date, and was first introduced a0704a8996 (diff-2e3836af182cfb375329c3463ffd91f8L117). Before that commit, there wasn't a problem because cs_main was held during the poll update.
Currently, the problem should be rare. But if 8937d99ce81a27ae5e1012a28323c0e26d89c50b from #17954 were merged, the problem would get worse, because the wrong cachedNumBlocks value would be set if the wallet was polled in the interval between a block being connected and it processing the BlockConnected notification.
MarcoFalke also points out that a0704a8996 could lead to GUI hangs as well, because previously the pollBalanceChanged method, which runs on the GUI thread, would only make a nonblocking TRY_LOCK(cs_main) call, but after could make blocking LOCK(cs_main) calls, potentially locking up the GUI.
Thanks to John Newbery for finding this bug this while reviewing https://github.com/bitcoin/bitcoin/pull/17954.

This requirement was introduced in the initial implementation when we were signing protx payload with the owner key (#2246). This was changed later when we implemented external collateral references (#2366). The owner key is not used for anything in ProTxReg but to get CKeyID since then which we can do by simply decoding an address instead. This simplifies masternode registration process by letting an Operator to issue `protx register_prepare` on its own instead of asking an Owner. An Owner still have to sign the message provided by an Operator with his collateral address to prove collateral ownership (and authorize masternode registration).
Note: `protx register_*` rpc will no longer accept privkeys for ownerAddress. Some 3-rd party software like DMT might need to be patched to work correctly with nodes running with this fix.
Made node sense to squash it into the related OptionsDialog commit of
the initial PR because this diff uses the wallet interface which gets
introduced one commit after the related commit.

* qt: Update the application font if the font family gets changed
* qt: Make sure recent transactions have the correct font family
Introduced because QListView is ignored in GUIUtil::updateFonts, so its base font family doesn't change, hence the recent transactions don't adjust because the painter's font doesn't change.
