Helix search results page should mention if no matches were found

[Alexander Köplinger]

Right now it displays a confusing view where it shows the empty results table including pagination buttons and "Results for 0-50 of 103 builds".

This makes it look like runfo broke but I think what happens is that there were 103 builds but none contained the search string?

Example query: https://runfo.azurewebsites.net/search/helix-logs/?bq=definition%3Aruntime+kind%3Arolling+result%3A%21succeeded+started%3A%7E2&lq=logkind%3Aconsole+text%3A%22foobar%22

Will clean this up.
