Merge bitcoin-core/gui#271: Don't clear console prompt when font resizing

7962e0dde8 qt: Do not clear console prompt when font resizing (Hennadii Stepanov)
d2cc339005 qt, refactor: Drop redundant history cleaning in RPC console (Hennadii Stepanov)
4f0ae472e2 qt: Untie irrelevant signal-slot parameters (Hennadii Stepanov)

Pull request description:

  On master, a console resize event will clear the prompt. To fix this, we store the content of the prompt and re-set it upon a resize. This preserves the prompt text throughout resizes. The text will still clear when you click the clear button, as it should.

  **Master**
