split groups of save history items that have different status results

[faush01]

Simple change to split groups of save history items when the status for items in a group changes.

I noticed that the status (icon) was only showing for the first item in a group, if there were say 150 saves and the last 30 failed then it would still show success.

Example of the changes:

Tested and working on Android 14, Pixel 6a.

Test 1 procedure:

• Started streaming book (let it buffer a bit, got a few sync events)
• Turned off server (lost connection but did not affect app connectivity)
• New save icon with red icon was created and counted

Test 2 procedure:

• Downloaded book
• Started playing, waited for a sync event
• Turned on airplane mode on phone
• Waited for next save event, new event was created as expected
• Paused, turned off airplane mode, synced with server

Do you need anything else from me on this?

Works as expected with Oneplus One, Android 11. Tested with same procedures as @nichwall
