Title: Workaround for $tag is not a object

I don't know why $tag is no object, but I did the following steps to produce this error:
1. Install Clip (for UI-Hook)
2. Install Tag
3. Remove standard tags and add one tag
4. Bind hook to Clip
5. Edit an existing entry
--> Loading failed with ```PHP Fatal error: Call to a member function getTag() on a non-object in /my/path/to/Zikula/modules/Tag/lib/Tag/Entity/Repository/TagRepository.php on line 50, referer: https://myurl.net/myClip/url```

If I print (with print_r) $tags from line 42 I get the following:
```
Array(
[0] => Array
(
[0] =>
[freq] => 1
)

[1] => Array
(
[0] =>
[freq] => 1
)

[2] => Array
(
[0] => Tag_Entity_Tag Object
(
[id:Tag_Entity_Tag:private] => 4
[tag:Tag_Entity_Tag:private] => gäste
[slug:Tag_Entity_Tag:private] => gaste
[reflection:protected] =>
)

[freq] => 1
