As reported in Slack, if a value is missing, `jq` returns `null`.
When run normally (e.g., `echo "${JOB}" | jq -r '.somekey'`), this becomes an empty string when the key is missing.
However, when run within a subshell (e.g., when assigning to a variable, such as `VALUE=$(echo "${JOB}" | jq -r '.somekey')`), the string `null` is returned.
Fortunately, `jq` allows specifying an alternative value if a value is missing or `false` or `null`, via the `//` operator.
This patch adds alternatives everywhere `jq` is invoked when assigning a variable.
