Summary: Added a retry mechanism when scanning fails, to prevent waiting unnecessarily long for the next scan. This usually happens when closing and reopening the applet, or when a scan was started by another component before opening the applet. Test Plan: * First enable debug logging, there is no UI feedback * Tested opening/closing the applet every now and then: wifis are scanned as early as NM allows * Tested switching to the NM KCM, then switching to the applet, then to the KCM again: wifis are always scanned as early as allowed Reviewers: jgrulich, ngraham, #plasma Reviewed By: jgrulich Subscribers: davidedmundson, plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D18896
