Podio API appears to be returning the incorrect type for user emails in grants

[enragedlemon]

Using the latest version of the Podio-PHP client for the API, calling PodioGrant::getfor( 'item', $itemid ) causes the following error notice:

Notice: Array to string conversion in /var/www/api/Podio/lib/PodioObject.php on line 162

When examining the data returned by the call (see snippet below), we notice that user mails has has been cast from array to string, causing a string of "Array" to be returned.

[user] => PodioUser Object
(
[_attributes:PodioObject:private] => Array
(
[userid] => 1234567
[profile_id] => 1234567
[name] => Joe Blogs
[link] => https://podio.com/users/1234567
[mail] => Array
[type] => user
)

This can be fixed temporarily by changing PodioObject.php[162] from

$this->attributes[$name] = $value ? (string)$value : null;

to

$this->attributes[$name] = $value ? ( is_array( $value ) ? $value : (string) $value ) : null;

Clearly, this isn't an ideal solution, and I suspect may need to be addressed elsewhere instead.

Andreas has addressed the error with this commit, but I don't think this addresses the underlying issue. The mails data is multi-part, as the user can have multiple account emails. As such, I feel this data should be returned as an array. That would mean that whatever on the API-side that is reporting the mail array as a string should be fixed 👍
