Change backup Frequency in config-panel is not applied

[xoddark]

Describe the bug

When change of the backup Frequency (OnCalendar) in config-panel, the change is not applied to system.

Context

• Hardware: Dedicated server ...
• YunoHost version: 4.3.6
• I have access to my server: Through SSH | through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: borg 1.1.16~ynh28

Steps to reproduce

• Installing borg with :
• with just ynh conf backup (enough to test)
• backup every fifteen minutes (for example) / set Frequency to : *:0/15
• Always mail (to know when backup is finished)
• Wait and see than a backup is done every hours
• Change borg backup Frequency to Daily
  1. Go to 'app borg' option
  2. Click on 'Config Panel' button
  3. Change Frequency to 'Frequency'
  4. Click on save
• Observe than backup is always done every fifteen minutes

And If you launch the command systemctl stop borg.timer on server, you have this message : Warning: The unit file, source configuration file or drop-ins of borg.timer changed on disk. Run 'systemctl daemon-reload' to reload units.

Expected behavior

When change in config-panel is saved, we expect than the change was applied. Yunohost should probably run the command (or equivalent) : systemctl daemon-reload

Just to add my +1 Before:

# systemctl status borg.timer
Warning: The unit file, source configuration file or drop-ins of borg.timer changed on disk. Run 'systemctl daemon-reload' to reload units.
