Improve Page picker to match both dot as a page name char and as a separator and suggest them both

The 'Go To' page picker currently takes into consideration typing characters from page name and not the page reference.

For example, currently when typing "Sandbox.W" it doesn't suggest 'Sandbox.WebHome' page.

It would be nice to match both dot as a page name char and also as a separator and propose them both in the suggested list.
