The model-update bounces already drop themselves when the repo is
switched mid-refresh (onUIThreadUnlessRepoChanged), but three bounces
that touch the UI without writing the model did not: refreshView's
render, the staging-panel refresh, and the stale continue-rebase prompt
dismissal. All three ran unconditionally on the UI thread, so a
background refresh in flight across a repo switch could render the old
repo's data (through a context object belonging to the now-replaced
context tree), or pop the new repo's popup based on the old repo's
prompt state.
Route them through onUIThreadUnlessRepoChanged too, so they're dropped
alongside the model writes they accompany. This also fixes the dismiss
bounce using the raw foreground OnUIThread, which ignored the background
flag every other bounce in a background refresh respects.
