Don't compute a nonsensical assigned task count for logged-out users

Summary:
When a logged-out user views the home page, we currently compute a meaningless "assigned tasks" count which just counts every open task. Don't do this.

Ideally `ManiphestTaskQuery` should get some tightening up too (that is, `withOwners(array(null))` should not select every task), but that might affect other stuff and the performance implications of counting every open task are affecting WMF, so just fix the immediate issue for now.

Test Plan:
  - Viewed homepage as a logged out user, no assigned task count.
  - Viewed homepage as a logged-in user, still saw assigned task count.

Diffusion - make projects work properly with commits

Summary: Fixes T3189. Now if you say #projects in a commit message they will associate nicely with the commit. Also we record transactions about all this project editing fun.

Test Plan: tested migration by associating some projects with commits and verifying they still showed up post migration. tested adding / removing projects by doing so from the UI, noting transactions written nicely as well

Allow device SSH keys to be trusted

Summary:
Ref T6240. Some discussion in that task. In instance/cluster environments, daemons need to make Conduit calls that bypass policy checks.

We can't just let anyone add SSH keys with this capability to the web directly, because then an adminstrator could just add a key they own and start signing requests with it, bypassing policy checks.

Add a `bin/almanac trust-key --id <x>` workflow for trusting keys. Only trusted keys can sign requests.

Test Plan:
  - Generated a user key.
  - Generated a device key.
  - Trusted a device key.
  - Untrusted a device key.
  - Hit the various errors on trust/untrust.
  - Tried to edit a trusted key.
