[Address Book] Search only works on formatted name with whitespace taken into account

[Michał Sawicz]

Steps:
* have a contact name with a nickname and formatted name set different to family or given names
  (needs to by synced from a remote source)
* search for the contact with "given family"

Expected:
* the contact is found and displayed with the nickname/formatted name

Current:
* the contact is not found

The search should probably be performed on many more fields (ORG, at least). Spaces should be used to split the search terms and perform an AND on the results.

------- UX comment --------

The desired solution is already in the original bug description:
"The search should [...] be performed on many more fields [...]. Spaces should be used to split the search terms and perform an AND on the results."

This is especially helpful users have several contacts with the same first name and want to search with additional keywords to distinguish them.
