Develop ContentResolver-based unit tests for vCard importer and fix vCard code

along with the tests

Make test code not only check the validity of VCardParser but also check
the validity of the data insertion part of ContactStruct class, using
MockContentResolver/MockContentProvider. With these tests, we are now really sure
vCard side appropriately sends vCard data into the resolver.

Fix ContactStruct so that it properly handles ORG property and TITLE property,
though it still does not see Group information. There's no vCard found which
uses Group and ORG and TITLE in convolted orders...

e.g. Current implementation misinterprets the following case, but we're not sure
whether any exporter emits data in this kind of complicated form...
group2.ORG:ComparyA
group1.ORG:CompanyB
group1.TITLE:TitleForA
group2.TITLE:TitleForB

Expected: CompanyA + TitleForA, CompanyB + TitleForB
Actual: CompanyA + TitleForB, CompanyB + TitleForA

Also change the parser part a little, so that some component can be reused via
the other part of vCard code.

Added several additional files for the tests, which ensures that
- ORG/TITLE properties are handled as we expect.
- PREF is appropriately handled and passed to the resolver as "IS_PRIMARY" flag.
-- We discarded the code which ensures that "IS_PRIMARY" is added to only one
   field in each type, after the local discussion (the duplication or no primary
   state should be handled by the resolver).
