/***
 * Running lerna with since and scope is not working as expected.
 * For example, running the command `yarn test --scope=@budibase/worker --since=master`, with changes only on `@budibase/backend-core` will not work as expected, as it does not analyse the dependencies properly. The actual `@budibase/worker` task will not be triggered.
 *
 * This script is using `lerna ls` to detect all the affected projects from a given commit, and if the scoped package is affected, the actual command will be executed.
 *
 * The current version of the script only supports a single project in the scope.
