Add support for disabled cron expression "-"

See original GitHub issue

According to the docs, db-scheduler supports

Spring-style cron-expression.

However, a Spring cron expression of “-” means the task will never run, which is useful for disabling a task in a local/test environment.

I tried this expression with db-scheduler, but it caused this exception:

Caused by: java.lang.IllegalArgumentException: Cron expression contains 1 parts but we expect one of [6]

Hoping this is solved with #286. Does that implementation work for you?
