TryGetable for Option<T> Should Handle Errors

[billy1624]

We should not ignore any errors when decoding db result.

match row.try_get(column.as_str()) { 
    Ok(v) => Ok(Some(v)), 
    // Error ignored
    Err(_) => Ok(None), 
} 

For example:

sea-orm/src/executor/query.rs

Lines 86 to 121 in e144216

	impl TryGetable for Option<$type> {
	fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, DbErr> {
	let column = format!("{}{}", pre, col);
	match &res.row {
	#[cfg(feature = "sqlx-mysql")]
	QueryResultRow::SqlxMySql(row) => {
	use sqlx::Row;
	match row.try_get(column.as_str()) {
	Ok(v) => Ok(Some(v)),
	Err(_) => Ok(None),
	}
	}
	#[cfg(feature = "sqlx-postgres")]
	QueryResultRow::SqlxPostgres(row) => {
	use sqlx::Row;
	match row.try_get(column.as_str()) {
	Ok(v) => Ok(Some(v)),
	Err(_) => Ok(None),
	}
	}
	#[cfg(feature = "sqlx-sqlite")]
	QueryResultRow::SqlxSqlite(row) => {
	use sqlx::Row;
	match row.try_get(column.as_str()) {
	Ok(v) => Ok(Some(v)),
	Err(_) => Ok(None),
	}
	}
	#[cfg(feature = "mock")]
	QueryResultRow::Mock(row) => match row.try_get(column.as_str()) {
	Ok(v) => Ok(Some(v)),
	Err(_) => Ok(None),
	},
	}
	}
	}

Encountered this issue on #60, where most of the errors silenced whentry_get() an Option<T> in Postgres.
