Title: Fixing PHP notice that got triggered when $clause['alias'] doesn't exist.

This expression
```
HAVING
change_id > :change_id
```
produces several tokens and couple of them are empty, so the `$clause` doesn't contain anything but
```
array (size=1)
'delim' => boolean false
```
Probably that should be fixed in tokeniser.
