Fix bridge policy raises an error when downstream_project is nil
What does this MR do and why?
This MR fixes RuntimeError on Projects::EnvironmentsController (#424145 - closed).
In the environment page, it serializes data for each environment, its latest deployment, and its manual actions (the other manual CI jobs that affect to the environment e.g. 15% rollout, 30% rollout, etc).
These manual actions started including bridge jobs since b4b5f918. This raises an error if the downstream project of the bridge jobs doesn't exist anymore, which is relatively edge case.
See #424145 (comment 1543046369) for more information.
