sqlite-net: NullReferenceException in SQLite.PreparedSqlLiteInsertCommand.ExecuteNonQuery(...)

Description:

I’m getting from time to time if I start my app a System.NullReferenceException: Object reference not set to an instance of an object. I’m unable to reproduce it, but once it happens once it will occur about 2 to 3 times in a row. After that the app starts again as expected. It could be that this error is related to #530 but I’m not sure. I’m accessing the DB heavily multithreaded.

Details:

• sqlite-net version: 1.5.231 occurs also on 1.4.118 and 1.3.3
• Implementation
• UWP target version: 16299
• UWP min version: 10586
