Test-like output when test file does not exist

[vadimdemedes]

The output is not what it should look like (latest master):

$ ava example.js

(example.js does not exist).

First of all, notice 1 extra line at the start & end of the output. And top-level CLI errors should be displayed as:

  ❎ Couldn't find any files to test

This is probably due to https://github.com/novemberborn/ava/commit/9dd03d5d2b20de48e72cb59e29573dd412201b1b (see #502). There's some variance between the reporters, looks like the verbose one should render a cross.

Maybe this particular exception should be treated differently in the mini reporter. Or perhaps a general case can be made when there is 1 exception and no tests where found.

[vadimdemedes]

No no, this kind of top-level output from CLI should be written without reporters, as those are fatal errors.

Not when watching though. It's legit to start a watcher even if there are no test files yet. Or to remove the only test file while the watcher is running.

What's the status of this? A simple edit to reporters/mini.js fixes the extra lines, but what about the cross? Also an easy fix in the reporter file.

[novemberborn]

If we can agree that these are not fatal errors then I think we can fix up the reporters.

Closing because this was fixed a while back in #704.
