Factory reset doesn't clear FSTAB network mounts from /etc/fstab

[prl]

If you have any FSTAB-style network mounts and do a factory reset, the mounts are cleared from /etc/enigma2/automounts.xml (the file is deleted) but the mounts remain in /etc/fstab.

When the T3 reboots after the factory reset, the mount is still visible in MENU>Sources, but it can't be seen or modified in MENU>Settings>Network>Mount manager>Mountpoints management, so the user can't modify or remove it through the GUI.

Reproduction steps

Create a network mount with Mount using: FSTAB. Check that the mount is accessible in MENU>Sources

Do MENU>Settings>System>Factory settings, and wait for the T3 to reboot. The mount is still visible in MENU>Sources and can be accessed, but is not visible in MENU>Settings>Network>Mountpoints management.

To recover, edit /etc/fstab to remove the network mount, and reboot.
