[messaging] Fix bugs occurring when filtering by strings or value ranges

The following bugs have been fixed:
- daylight saving time was not taken into account when filtering by
  timestamp attribute with AttributeRangeFilter
- AttributeRangeFilter did not work with null/undefined range limits
- isBetweenTimeRange did not work properly with lower limit close to the
  minimal value of time_t type variables
- filter with an empty string matchValue never matched other strings

[Verification] Subtestcases from TCT tests added in
https://review.tizen.org/gerrit/#/c/test/tct/web/api/+/199159/
that used to fail due to the described bugs now pass.
