addInlineJs parameter type mismatch between v1.5.10 and v1.6.0

[matt-j-m]

In v1.5.10 the following worked:

$assets->addInlineJs($json, null, null, 'application/ld+json');

As of v1.6.10 the above triggered an error expecting the last param as an array, not a string.

array_merge(): Expected parameter 2 to be an array, string given in system/src/Grav/Common/Assets/Traits/LegacyAssetsTrait.php line 54

Have applied following work-around and tested on v1.5.10 and v1.6.14:

$type = array('type' => 'application/ld+json');
if (version_compare(GRAV_VERSION, '1.6.0', '<')) {
    $type = 'application/ld+json';
}
$assets->addInlineJs($sd, null, null, $type);

Possibly related to open issue #1687
