SqfliteDatabaseException attempt to write a readonly database (code 1032 SQLITE_READONLY_DBMOVED[1032]))

## 🐛 Bug Report

When using the flutter_cache_manager within Dart 2.15 within Flutter 2 I get sometime this Fail with SQLite.

Error:
SqfliteDatabaseException
DatabaseException(attempt to write a readonly database (code 1032 SQLITE_READONLY_DBMOVED[1032])) sql 'UPDATE cacheObject SET url = ?, key = ?, relativePath = ?, eTag = ?, validTill = ?, touched = ?, length = ?, _id = ? WHERE _id = ?' args [https://asdf.de/img/start_aktion-1_mobil-opti...., https://asdf.de/img/start_aktion-1_mobil-opti...., 57dcb0d0-79e7-11ec-bb36-436c12859413.png, W/"16304a-17dc2bf19ff", 1643284306013, 1642679987235, 1454154, 1, 1]

### Expected behavior

I would like to have a non throwing Error behaviour with the Cache Manager.

### Reproduction steps

Call within InitState method something like this (async):

mainProvider.retrieveStartPageData(mta).then((value) async {
if (value != null) {
if (mainProvider.myHi.length > 0) {
for (var headerImage in mainProvider.myHi) {
await DefaultCacheManager().getSingleFile(
'${Env.value!.imgUrl}${headerImage.imageMobile}');
}
}
}
});

### Configuration

Dart: 2.15
Flutter 2.5

**Platform:**
- [x] :iphone: iOS
- [x] :robot: Android

Start by reproducing the async DefaultCacheManager().getSingleFile calls from initState on iOS and Android with the stated Dart and Flutter versions, then trace the SQLite update that emits SQLITE_READONLY_DBMOVED. Done means the intermittent failure is understood and the cache manager no longer throws in the reported scenario, with regression coverage added.
