We currently lose RemoteWebProgress event listeners when switching between local and remote processes.

This came up while working on bug 1578465 and bug 1585777.

Attachment: Bug 1586050 - Don't blow away progress listeners when switching between local and remote processes, r=kmag

Whenever we do a process switch, the <browser> gets a new WebProgress instance.
When that happens, we currently handle transferring listeners from one
RemoteWebProgress instance to another, but not from a local to remote, or vice
versa. This patch changes that by tracking listeners added to the <browser> and
manually re-adding them after a process switch occurs.
