Importing (large amounts of data) with collection links stalls

[eternalflamez]

This is due to this findOne call not actually resolving on error, adding a .catch to this block would solve the issue:

For instance:

App.callmodule('collections:findOne', [field.options.link, filter]).then(function(data) {

if (data.result && data.result._id) {
    //TODO add support for multiple imports
    var entry = {_id:data.result._id, display: data.result[field.options.display] || data.result[Filter.collections[field.options.link].fields[0].name] || 'n/a'};
    $this.resolve(field.options.multiple ? [entry]:entry);

} else {
    console.log("Couldn't find a collection reference for "+value);
    $this.resolve(null);
}
})
.catch(() => {
    console.log("Couldn't find a collection reference for "+value);
    $this.resolve(null);
});
