[Bug 1826223] [NEW] lvm not detected in initramfs after upgrade to 19.04

[Nowres Rafid]

Public bug reported:

Hello,

After upgrading to 19.04, I was unable to boot into linux 5.0 kernel, I got an lvm not found message after providing my luks passphrase
I fell back to an older kernel version to be able to boot into my system

Here is my grub entry:

```
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-a895fab8-6c63-4707-ace2-eaf1f4f3e02a' {
	recordfail
	load_video
	gfxmode $linux_gfx_mode
	insmod gzio
	if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
	insmod part_msdos
	insmod ext2
	set root='hd1,msdos1'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  7fc86ec8-e5ac-4a11-9153-622e7a9ace07
	else
	  search --no-floppy --fs-uuid --set=root 7fc86ec8-e5ac-4a11-9153-622e7a9ace07
	fi
	linux	/vmlinuz-5.0.0-13-generic root=/dev/mapper/vg00-root ro  nosplash
	initrd	/initrd.img-5.0.0-13-generic
}
```
