Fix bug: browser action button disappears when loading a new extension. This was happenening because BrowserActionContainer, on receiving notification about an extension load/unload/change, deletes all BrowserAction views, re-adds all the views again, and asks the toolbar to SetBounds for the BrowserActionContainer. However, during deletion, it does not re-set the bounds. As a result, when SetBounds is called by the toolbar again, it does not see any changed in BrowserActionContainer, and does not layout again, causing all the browser actions to disappear. The solution lies in forcing  Layout() after SetBounds() in ToolbarView.
