* chore: fix lint warnings
* chore: another try at python import errors
Looks like the problem is that dbus_mock.py is running as
a script but living in the `lib/` directory where it's part of a
module. Moving it up into the `script/` directory seems to
solve the issue.
* Removes un-used and non-functional code coverage helpers
* Removes un-used release script aliases
* Moves TLS to a lib folder for cleaner directory structure
* Implements start.py as start.js for the GN build
* Adds a re-usable getElectronExec helper for future scripts
* Refactors spec runner to use the helper
