[EGD-5317] Module-db UT solved

Vfs init.
Convertion time string to unix time returns 1 hour later than should.
DatabaseInitializer stub that just creates empty dbs with table
structure but without data. Notification table initial records moved
to Database Initilize section. UT run with a stub of Database
Initialize - new test section introduced to test original
initializer: test-initializer.
Added missing data for contacts db to run the sorted list test
and test fix.
