Merge JoinMarket-Org/joinmarket-clientserver#1013: Reorder the tabs in Qt

bc71997058 Reorder the tabs in Qt (Wukong)

Pull request description:

  The current ordering of the tabs in Qt feels very strange. For example, the "Settings" tab is usually the last tab in most applications, while it's the 2nd tab in JoinMarket-Qt.

  This PR reorders the tabs from "JM Wallet, Settings, Coinjoins, Tx History, Coins" to "JM Wallet, Tx History, Coinjoins, , Coins, Settings".

  I made the new ordering of the tabs by consulting the Electrum wallet, which has the tab orders of "History, Send, Coins".
