Prevent users from removing task titles with "Bulk Edit"

Browse source 
Summary:
See downstream <https://phabricator.wikimedia.org/T209449>.

The "Bulk Edit" flow works with `setContinueOnMissingFields(true)`, so `newRequiredError()` errors are ignored. This allows you to apply a transaction which changes the title to `""` (the empty string) without actually hitting any errors which the workflow respects.

(Normally, `setContinueOnMissingFields(...)` workflows only edit properties that can't be missing, like the status of an object, so this is an unusual flow.)

Instead, validate more narrowly:

  - Transactions which would remove the title get an "invalid" error, which is respected even under "setContinueOnMissingFields()".
  - Then, we try to raise a "missing/required" error if everything otherwise looks okay.

Test Plan:
  - Edited a task title normally.
  - Edited a task to remove the title (got an error).
  - Created a task with no title (disallowed: got an error).
  - Bulk edited a task to remove its title.
    - Before change: allowed.
    - After change: disallowed.
