v0.19.0-0 QA Review

[smashwilson]

QA Review to prepare for the v0.19.0 release. Let's build Atom with the v0.19.0-0 prerelease version of this package and ensure that all of the bugs we wanted to fix are fixed properly, and that there are no unexpected complications from snapshotting or asar-bundling.

The work we're testing can be found in the merged column of the project board for this sprint.
