The tabGroups.onRemoved / onCreated / onMoved event depends on the isAdoptingGroup / removedByAdoption flags to identify tab groups that are adopted by another window. Although this flag is set for the `gBrowser.adoptTabGroup` method, it is not in the `gBrowser.replaceGroupWithWindow` method, which results in incorrect events. This patch fixes the issue by setting the isAdoptingGroup flag in `gBrowser.replaceGroupWithWindow`. Differential Revision: https://phabricator.services.mozilla.com/D248327
