Test: Query an addressbook for vcards having an EMAIL property that does NOT end in @abcd.com
Expected result: Only contacts with an EMAIL property that does NOT end in @abcd.com are returned.
Actual result: SOGo returns contacts with an EMAIL property ending in @abcd.com, i.e. it ignores the negate-condition="yes" attribute to the text-match.

RFC 6352 references:
  - 10.5.4 (text-match XML element): The "negate-condition" attribute is used to indicate that this test returns a match
    if the text matches, when the attribute value is set to "no", or return a match if the text does not match, if the
    attribute value is set to "yes".
