fix: push log messages to the message bar from the main thread - #127

QTimer.singleShot(0, func) runs func on the calling thread, not the Qt main thread. A log message with push=True from a background task (for example the thickness calculator) changed the QGIS message bar from the worker thread, and QGIS stopped responding when the task ended. Send the message bar change to the main thread with a queued signal.
