Support search result annotation on whole canvas

Some of the results target the whole canvas (not a #xywh region of it).

{
resource: {
@type: "cnt:ContentAsText",
chars: "..."
},
motivation: "sc:painting",
@type: "oa:Annotation",
@id: "http://scta.info/iiif/pp-sorb/search/annotations/prIV-sqtlch",
on: "http://scta.info/iiif/pp-sorb/canvas/S212v"
}

This means they fall foul of this regex in SearchResult:

this.canvasIndex = provider.getCanvasIndexById(resource.on.match(/(.*)#/)[1]);

(manifest: http://scta.info/iiif/pp-sorb/manifest)

For this result there is no region to paint. Would look odd to paint the whole canvas; but how to convey to the user that the whole page is the result?

@edsilv I think this may be the same issue as what I reported in slack. Not including the xywh fragment results in this error:

TypeError: e.on.match(...) is null app.js:9:6008

Work around is to use "#xywh=0,0,0,0"

This should be fixed if it's still an issue. Many anno search results will target the whole canvas - search-within isn't just for OCR-generated data, it could be a textual description of a photograph, for example, which the search-within could find within an album of 500 photos.
