some qt arguments want int, not float after python 3.8 -> 3.10 upgrade

[molecular]

I upgraded my python virtualenv for electron-cash-slp and ran into errors like this:

Traceback (most recent call last):
  File "/home/nick/bitcoin/electron-cash-slp/./electron-cash", line 594, in <module>

    self.gui = gui.ElectrumGui(config, self, plugins)

  File "/home/nick/bitcoin/electron-cash-slp/electroncash_gui/qt/__init__.py", line 776, in _start_auto_update_timer
    self.update_checker_timer.start(interval)
TypeError: arguments did not match any overloaded call:
  start(self, int): argument 1 has unexpected type 'float'

upstream fix:
