Added fallback if searchresult contains error on initial query

Implements #353

I like the idea of switching on error, but not a fan of doing a test request. Also, it needs to be implemented in files_fulltextsearch instead.

I will have a look during the conf/hackweek

[newhinton]

@daita We can discuss it in person then! ;)

[ArtificialOwl]

Sure ! this is the whole interest of the conf !

in the meanwhile:
https://github.com/nextcloud/fulltextsearch/blob/master/js/fulltextsearch.v1.navigation.js#L293-L296
is called when
https://github.com/nextcloud/fulltextsearch/blob/master/js/fulltextsearch.v1.api.js#L54

So, if you create a onError method in https://github.com/nextcloud/files_fulltextsearch/blob/master/js/files.js#L219 it should be called when there is an issue requesting the elasticsearch (and/or the nextcloud)
