Fix: EnableTags=true and FilteredTags="" produces dot separated result

[lexx-bright]

Do not split empty string. Otherwise the result is a slice with one element - the empty string. The rest array length checks will consider we have tags to filter.

[msaf1980]

May be also add (for replace spaces if tags passed like "tag1, tag2" instead of "tag1,tag2" ?
