Kevin O'Connor 9f2a025762 bltouch: Don't assume reset will do a pin_up in test_sensor()
Some clones don't raise the pin on a reset and the ANTClabs BL-Touch
sometimes doesn't raise the pin either.

Rework the (infrequently called) sensor test code to always issue a
pin_up command before the touch command.  Also, perform a reset and
retry if the sensor test fails.
