playback: revert the restored session prepare

Preparing the restored window on launch was meant to make the paused
session reachable from Bluetooth and Automate. The follow-up on the issue
shows the notification appears, but the car's play command still does not
reach the app until the phone is unlocked, and the speculative prepare
buffered up to 50 seconds of the restored track on every launch while
claiming the media controls whenever the app opened.

Removing the prepare also removes the error gate it needed, which could
hide genuine playback errors while paused.

Reverts #230.

+## What's new
+
+- ReplayGain: normalizes loudness from the tags your server reports. Auto, the default, uses album gain for album queues and track gain for playlists, singles and shuffles. Playback settings also offer track gain, album gain, off and a preamp
+- Artist pages show an expandable biography, artwork from the server or built from the artist's albums, and separate sections for album credits and appearances
+- Sort lists can use regular names (the default), sort names, or sort names only for names without Latin letters
+- Improved handling for albums and tracks with multiple artists, including their names in song subtitles, the queue and info dialogs
+- Info dialogs in album, artist and playlist menus, listing credited artists, sort names, owner and sharing, and play and download details
+- Keep the screen on while now playing is open setting, off by default (thanks @chiangww!)
+
+## Fixed
+
+- Album and artist scroll positions survive navigating away and back
+- Search keeps its query and focus when you return
+- The library tab strip scrolls, so the settings gear is never squeezed out
+- Notification progress for streams of unknown length, such as Opus/Ogg transcodes
+- Album grid no longer shifts covers after a scrobble reloads the list
+- Now playing screen: artwork wraps with repeat, and cover shadows are no longer clipped
+
+## Performance
+
+- Faster library sync on servers without `search3`
+- Artist lists and downloads stay fast on large libraries
+
+**Full changelog:** https://github.com/austinried/subtracks/compare/v3.0.0...v3.1.0
