Use ToString when value returned from GetValue is not a string type.

#406 Changes Row.GetString to mimic the MySql.Data GetString by using ToString() for non-string type column.

The current (strict) behaviour is by design; I plan to add more GetValue/GetX tests to https://github.com/mysql-net/AdoNetApiTest to check the common approach to this across other connectors, and will wait on making any decision on this until then.

Is a culture-sensitive conversion the right thing to do here?

[robertbeuligmann]

It is the same conversion used in MySql.Data https://github.com/mysql/mysql-connector-net/blob/fcb0843b4140e648195be7ff2ef0f20dda14e45b/Source/MySql.Data/datareader.cs#L693

[robertbeuligmann]

Having GetString not automatically convert columns to string is a major blocking change from the default MySql.Data implementation for the project I would like to convert to MySqlConnector.

[bgrainger]

Opened mysql-net/AdoNetApiTest#4 for the data type conversion investigation.

[bgrainger]

Closing this since a culture-sensitive conversion of a retrieved value to a string is likely to be buggy, and since GetValue(x).ToString() is a possible workaround.
