Subject: options, opentrack: fix migrations with tie_setting

Migrations only ran after `tie_setting()' handlers were done, clobbering
the settings that were about to be migrated. Applying QSignalBlocker to
few comboboxes isn't enough as it affects everything touched by
`tie_setting()'.

Split reload and notify phases in the options system.
