App doesn't start without any error message when the configuration file is malformed in certain ways

[mlopatkin]

While we try to recover from malformed JSON data, it doesn't always work. For example, this fails:

1. Run version 1.1 (nightly)
2. Create a highlight filter
3. Close the app
4. Run version 1.0.1

Expected result: something visible happens

Actual result: nothing happens, app just doesn't start.

With -d we can see the logs:
