/**
* Checks if update is possible, saves local changes and updates all roots. In case of error shows

*
* <p>Perform update on all roots. 0. Blocks reloading project on external change, saving/syncing
* on frame deactivation. 1. Checks if update is possible (rebase/merge in progress, no tracked
* branches...) and provides merge dialog to solve problems. 2. Finds updaters to use (merge or
* rebase). 3. Preserves local changes if needed (not needed for merge sometimes). 4. Updates via
* 'git pull' or equivalent. 5. Restores local changes if update completed or failed with error.
* If update is incomplete, i.e. some unmerged files remain, local changes are not restored.
