[10.x] Truncate sqlite table name with prefix

[kitloong]

When truncating an SQLite table, it should reset the auto-increment value.

This PR fixes the failure to delete from sqlite_sequence when a table name is prefixed.

Step to reproduce

Config::set('database.connections.sqlite.prefix', 'prefix_');

DB::table('users')->insert(
    [
        'name' => 'John Doe',
    ]
);

DB::table('users')->truncate();

DB::table('users')->insert(
    [
        'name' => 'John Doe',
    ]
);

$user = DB::table('users')->first();

Expected behaviour

$user->id === 1

Actual behaviour

$user->id === 2
