Smarti widget: Provide "can not help"-information

[mrsimpson]

as per #200, queries are now always being built - but if there's no query to be executed (e. g. since no token could be extracted), there should be a meaningful information on the widget that Smarti cannot help at the moment

[westei]

depends on #217

[ruKurz]

Isn't this a duplication of: #220 or the other way around?

[westei]

if @mrsimpson agrees we can merge this into #220

[Peym4n]

See #220 (comment)

[mrsimpson]

How does the i18n address this issue?

[westei]

If the widget does not have Tokens for a Query is shows the "can not help" message. Doing it on the server side is only part of the story. For sure one could mark a query as "incomplete" if no Tokens are available, but in the End the WIdget decides if tokens are assigned to a Query. So even if if Smarti things their are Tokens available the Widget might still not assign any Tokens (e.g. because the User removes a token). So the final decision is anyways by the widget so we need to have this logic anyways in the Widget.

@mrsimpson when I first sent that comment I mistakenly linked another irrelevant comment (i18n) but then I edited it. The linked comment describes what the solution to this issue is.
And as I believe that #220 is a duplicate of this issue I closed this one.

@mrsimpson can you check/update the state of this issue. Especially why have you moved it to the backlog? I am unsure how to proceed.

[mrsimpson]

I moved it back to the backlog since we effectively have no option to understand whether Smarti can actually help to facilitate the conversation or not.
I thought of having a property per query provider which allows the UI to react on it.
You commented this extensively in #226.
maybe we should close both of them and formulate a better story, also based on your ideas.
I take a step forward and close this one, at least in favor of #226
