c13cb6e62441c499c2dca6b899c67f2c3e9208fe Handle output placeholder missing backing file
In preparation for this CL:
https://chromium-review.googlesource.com/c/infra/luci/recipes-py/+/1777143
Currently, if no test step data is provided for a step that uses an
output placeholder, the placeholder evaluates to an empty string. After
that CL lands, the placeholder will instead evaluate to None, breaking
any non-mocked code that assumes a non-null placeholder result.
There were dozens of places where these env var fetches would've needed
mocking, so I figured it was easier to just silently handle the case
where the placeholder backing file doesn't exist. Especially for trivial
cases like these environment variable fetches where the backing file is
a temporary file created just for that step (no `leak_to` argument
specified), it should be impossible for the backing file to not exist
unless you're doing some really weird stuff.
