Requirements

• Filling out the template is required. Any pull request that does not include enough information to be reviewed in a timely manner may be closed at the maintainers' discretion.
• All new code requires tests to ensure against regressions

Description of the Change

• Use atom.packages.hasActivatedInitialPackages() (and the relevant hook) to determine when to populate the Timecop view
  • Show Loading… before packages have finished activating
  • Prevents Timecop from improperly showing only a few packages activated due to the process.nextTick call
• Remove optional Workspace methods in TimecopView that were just stubs

Alternate Designs

I noticed that there was also an atom.packages.hasLoadedInitialPackages. I'm going to experiment with that to see if we can use that to split up the view loading.

Benefits

Code savings and more accurate Timecop view

Possible Drawbacks

None.

Applicable Issues

None.
