tests: More scan result flushing to make testing more robust

Test case sequence 'scan_chan_switch ssid_utf8' was failing due to a
scan result surviving from the first test case to the second and the old
entry ended up breaking check for the UTF-8 flag. Fix this by explicitly
flushing old scan results.
