Quartz: Jobs do not resume

[Yarik2308]

Same as in #1079 but jmix version 1.4.4
add spring.quartz.auto-startup=false in properties. Jobs are pauesd on application start.
If u try to resume job u get jobResumed notification but it stays paused.
Execute now button also do not run job.

Property spring.quartz.auto-startup=false keeps Scheduler from underlying Quartz library in standby mode.
In this mode Scheduler can't fire triggers and execute jobs.
Jmix Quartz addon is designed to work with active Scheduler.
So if you use this property you have to call Scheduler#start() (autowire org.quartz.Scheduler) somewhere before you are able to execute jobs.

Possible further improvements:

1. To prevent misunderstanding:
   1. Display Scheduler's state.
   2. Disable corresponding buttons if Scheduler's state doesn't allow to perform these actions.
2. Support additional features
   1. Add buttons to control Scheduler's state (start, standby).
   2. Research availability of immediate execution of some job without startup the entire Scheduler.
