Describe the bug

After the update to Version 1.28 the syntax of my filters has been changed.
There seems to be a new syntax for filters when working with intitle and 'composed keywords'
I am trying to follow that syntax but FreshRSS automaticly changes it after pressing submit.

To Reproduce

1. Create a new label
2. Add Filter actions
   intitle:OneWord OR intitle:'two words'
3. Press submit and it changes to
   intitle:OneWord OR (intitle:"two words")
4. Press submit again it changes to
   intitle:OneWord OR (intitle:"two words")
5. And so on and so forth
