Implement sorting of query history by name, date, and result count

[edoardopirovano]

This pull request addresses #767 by introducing three ways of sorting the query history view - by a query's label, by the date the query was run, and by the number of results the query produced.

This is a little confusing. The alerts table has 33 results in this example, but the #select table has 3906 results. I think people would expect that the result count matches the number of rows in the default table (in this case, it's alerts).

I'm not entirely sure why there is a difference here. I'm just running the example query from the starter repo:

/**
 * @name Empty block
 * @kind problem
 * @problem.severity warning
 * @id javascript/example/empty-block
 */

import javascript

from BlockStmt b
where b.getNumStmt() = 0
select b, "This is an empty block."

It would be nice if we could get the counts for the default table, but I'm not sure how easy this is without loading the sarif.

Looks good. And is working for me.

Can you squash and rebase your commits?

[aeisenberg]

Sorry....a few more changes. Just noticed them. If a query has an error, the result count is -1. That should not be displayed in the UI.

Looks like -1 is being set in the code. Can you change this to 0?

Thanks for the quick turnaround.
