Rewrite auto-update

Everything now happens in main.ts, in the bootstrap family of
functions. The current flow is:

* check everything only on extension installation.
* if the user is on nightly channel, try to download the nightly
  extension and reload.
* when we install nightly extension, we persist its release id, so
  that we can check if the current release is different.
* if server binary was not downloaded by the current version of the
  extension, redownload it (we persist the version of ext that
  downloaded the server).
