Save timeline in /test folder

[passsy]

When a test fails, it is hard to backup the timline HTML files in the temp directory. It would be better if those files would be saved somewhere in the /test folder.

Possible locations

• /test/.spot/<pathToTest>/test_x_timeline.dart
• /test/<pathToTest>/.spot/test_x_timeline.dart

Naming the files like the tests and saving it always in the same location would allow reloading the browser when a test ran.
But it would disallow comparing screenshots from previous runs (which would be deleted).

What about putting them into .dart_tool/spot/<pathToTest>/test_x_timeline.dart?
