Application crash at DropCollection

[InesCodMon]

Version
v5.0.18 and v5.0.19 /MacOS/.NET Standard 2.0

Describe the bug
I want to clean up the database (remove all collections and their content). But an error occurs when DropCollection is called the first time.

Code to Reproduce
public void CleanupDatabase()
{
IEnumerable listOfCollections = _db.GetCollectionNames();
foreach (string item in listOfCollections)
{
Console.WriteLine("COLLECTION" + item.ToString());
_db.DropCollection(item);
}
}

Expected behavior
All collections should be removed. The above code is expected to work the same as it does in version v5.0.17.

Screenshots/Stacktrace
The below error occurs when the DropCollection method is called.

LiteDB.LiteException: The current thread already contains an open transaction. Use the Commit/Rollback method to release the previous transaction.

I encountered the same error while migrating from v5.0.17 to v5.0.19

I tried both Commit and Rollback before performing the drop, but it didn't work. I think for now I'll revert back to version 17.
